Usually because we follow the rules and do not like it if someone else does not.

I park as far away from the store and anyone else possible because I have a nice car and I would love to keep it that way.
It always amazes me how often a huge pickup will park right beside me when there’s a whole parking lot.

Next time... Just go to Walmart!

Head to the kitchen items and get a basting needle setup (for injecting flavor into meat) and then over to the sporting goods section to get a bottle of fox urine.

Load the basting syringe with fox urine and stick it through the rubber weatherstripping of the car to spray all over the inside and on the upholstery. Of course this works great if it is a really hot day... But still smells bad on a cold one. When you pull the needle back out you will leave absolutely no mark anywhere and the person will be wondering how you did it.

Do you pay a premium for that extra space? Most apt complexes and other developments where there is assigned parking typically leaves guests with a select few spots. If I had to pay an extra premium to ensure my visitors had a place to park I'd sure as hell be territorial. LOL!

That's when it's fun to block their car in ...
"ya wanna park here ? STAY !"

lol at our office building, we have no assigned parking spaces...and we have more parking spaces than tenants but somehow, we all have our own designated parking spots...I think it is a weird thing as well...sometimes I want to park closer to the building, but I don't want to take the spot where the grey Honda accord parks...I won't be towed, obviously, but out of some weird parking space respect, I park in my spot...third bush on the north side...

Next time do not leave a note. Have it towed. HE (she?) should have left a note. And if you see the same car, have it done immediately.

Those of us who believe in civility and respect, sometimes feel indignation at these trespasses, and justifiably so. We give respect, we expect it in return. Unfortunately, there are many out there that were not raised with the same principles.

I live across the street from a Catholic church. One Sunday morning my son went outside to find one of the parishioners blocking our driveway. He talked to the church and told them it was bad enough that they park all around the house, but NEVER block our driveway again or the car will be towed. So far, we haven't had any issue.

I just have a little Ford Focus and can usually fit in any spot. But I get super annoyed if 2 vehicles hug the yellow line on either side of a space so that I can’t even fit my little car there

Because you captured it. Primal lizard brain kicks in defend what you capture.

I'm worse. There is just enough room on the public street in front of our house to park one car. But! It's dangerously close to our mailbox.. DANGEROUSLY CLOSE. Whenever anyone parks there, I track them down and tell them; YOU'RE BLOCKING MY MAILBOX. MOVE YOUR CAR." The neighbors are good natured and tell any and all guests/workers to not park in front of old man "Bigpaw's" house.....

Because our vehicles are an extension of ourselves?

I don't know why but it pisses me off to see someone in "my" space at work. My is in quotation marks because I do not have an assigned space; it just happens to be the one I chose as mine

I feel frustrated even if it is an unassigned stall at work. I park in the same stall all the time, every day and I'm even early to make sure of it. When my routine is broken when my stall is gone it throws off my day.
When people used to park in my second stall at an old apartment I would leave a friendly note the first time. The second time I towed them out of it.

Gee, I hope it's the end, not the beginning of something

Wow, that's some aggressive behavior. I think I would have written a note that said something like: "please find another spot to park by xx/xx I have company coming, or I have to tow your car". I would write a much different note if it wasn't where I live or if the spot was nowhere near my car. Then I would agree with the aggressive approach.

We must not encourage rude behavior,good job

I was moving in to my house, and a neighbor two houses away told me my van - in front of MY house- was in his parking space. Two years later, when out to dinner with his hair dresser, she told me the street i live on is full of real jerks, then told me of the parking fight i had on day one. Needless to say, when i got home, there was another fight in the neighborhood.

Because you pay for the space.

we are creatures of laws and rules then we try to cerconvent them by ignoring them thinking it makes us rebels or bad people. We pay rent on those spots so we need to have them for our use. I found aprtment mangement do not enforce the rules.

I park far away because it's better for my health. Light green eyes I sometimes find a huge vehicle parked beside me. Fortunately I parked far enough away that I can just drive forward and not worry about it anyway. More than likely the people that Park beside me just want to walk as well and why they didn't park in a Solo spot is beyond me but it doesn't really make me angry if they do Park beside me. I drive an older car perhaps that's the reason I'm so Live and Let Live.

I don't mind walking... so I don't look for parking closer to the store... I am annoying to many normal people... and I don't mind... but I admit having forgotten where did I parked on a night of party, dancing and drinking... Not Good.

Whoever parked there did not ask you, but just took what he wanted. He intruded on your turf, and that's nearly always annoying. And he was a sulky brat when you called him out. You summed it up in one word: Jerk.

...what your anger is is about tribalism...mine over yours etc...In all honesty we all get like that at times, either over something as small as a parking space or as large as denying an entire group or race (which is technically only a human construct to differentiate classes of people via physical features, yet we never call dogs of differing backgrounds races of dogs).
