I've got 20 acres in the sticks and keep about 2 acres mowed so I have bonfires weather permitting. And plenty of space for those with kids and even have a dirt oval track for go karts.

Warn them in advance that I have the flu. They appreciate that.

We have a kind of open house every weekend, at least every 2nd weekend is considered a "gathering" Friday night is usually board games and annoyingly too much drinking, Saturday night is no drinking and computer games. The nights culminate with a bonfire on the beach, the bbq runs most of the time when they get hungry. I should point out that I do not enjoy this at all which is why the bonfires are now at the beach whereas previously they were in my backyard. Bloody kids.

I sit here and people always come interrupt the solitude. I understand they want to be around my stepson and me, but it gets old. I have very little exposure to others in my work, so that’s cool. I’m fine with that, and y’all give me enough interaction otherwise.

My two best friends live on the same property as me, (my brother and I both own the property and the four houses on it), so I see them whenever I want and we get together all the time.

I have dinner every other week with my kids at one of our homes. So every two months my house gets extra cleaning. I have a friend from former job I meet up with every couple of months. I have a Humanist group I meet with. And I have an office I go to. I am an introvert and given my druthers there are times I'd be a hermit.

I try to have themed parties... OK, OK, I like excuses to have a party. Lately, Winter Solstice. New Year's, Ground Hog Day, Valentines Day.

@birdingnut post has just reminded me of an occasion 30 years ago when I persuaded a woman who was making a birthday cake for her husband's 40th birthday not to make the cake in the shape of two large breasts - she had delightful handful sized breasts. Instead we made together a large dark brown chocolate penis and testicles cake complete with cream coloured centre. She even found and arranged alongside a "sperm" shaped candle for igniting.
The party was held in a country golf club. I was told that the women attending nearly rioted wanting to know from the now delighted wife "who had modelled for the cake?" - they had probably all seen the size of the philandering husband whose party it was and so knew it wasn't him.
Lol.

In a previous life, when I was still with my husband, we had some parties. We hired a bartender and had a maid, prizes, and food. It gets really expensive really quickly. It was a good time, but that money could have gotten me that much closer to retirement.

Lol.When I moved 3 years ago I gave invitations to about 50 neighbours and members of a local social/learning institution that I attend. I offered not a housewarming party but a series of dinners for 6-8 people in order to get to know people. I received 2 RSVP's but neither indicated what date they preferred. So it never happened. I compare this to my 50th birthday when I invited 50 people to celebrate with 5 courses served alfresco in the middle of winter. This was when I was living off grid in another state. Cooking was on my two ring bottled gas stove and a one ring gas tank burner. 45 invitees and 2 interlopers turned up for the 5 hour event. No one got food poisoning, all said they enjoyed the food many having second helpings and a fire was built in an empty 50 gallon drum to warm the area up.
It was one of the few, if not the only, party when I didn't stress out.

I love game night parties rarely throw them anymore. I'm mostly an introvert these days.

Wow. Seriously?
You should consider offering your party planning services to the non-hosters. You could probably charge what you wish.

Shoot, some people make businesses of taking down and putting up holiday decorations for people.

I socialize by walking out the door of my apartment. I am surrounded by kind, polite Thai people, and am friends with vendors, building staff, neighbors, etc and we fall into step together even when I'm out walking, to catch up.
When working, I laugh and talk with Thai teachers and joke around with the Thai students.

But to socialize in English, I have to go online!

Meetups.com, mostly hiking and kayaking. I just recently rediscovered contra dancing. These things get me out of the house and interacting face to face with real live people.
