My brother in law is very extroverted, and he cannot stand to be alone. Drives him nuts. My sister is sort of in the middle, enjoys and needs solitude when working. I'm at the other end of the spectrum; complete isolationist! I can only stand other people in small doses!

My late friend Dave was the ultimate extrovert. One time he came to visit me in Montana and I wanted to take him to my favorite place - Two Medicine, in Glacier National Park. For me, it was paradise, but after a couple days of no cell service and no crowds Dave was going nuts. We later went into West Glacier, and Dave beelined it to a pay phone, because he "had to find out about" a party that was happening that night 2,000 miles away. I miss Dave. But for him I would have never met people.

Most of my friends are extroverts and there is always something going on Happy hours after work week end parties so I couldn't tell you . I'll ask the next time I see one . I can't take too many people at one time and might only go to one or two parties a year which I feel obligated to go to .

This "stir crazy" feeling that extroverts get when deprived of social stimulation explains a lot of behaviour I've seen...or been the victim of.

My workplace is busy and loud, and everybody is on top of everybody else most of the time. Even so, some people who won't go to lunch until a friend is ready to join them.
