When there where different groups of people, I used to jump between them in high school recess, or to talk with someone specific, or sitting alone.
Even today - at first I started going out drinking after high school, so at first it was with some groups, then I joined others, and basically I guess that even while socialising, it was important to be me. So now I just like going to same pub every time, where I feel at home, and the workers used to be customers, and the customers are loyal, in all ages... I like to come there, perhaps inviting someone in the way, and just sitting and waiting to see how it goes.
I always socialise today outside - 'cause of drinking - but I like seeing different people. Meeting new ones, hear something I didn't know before maybe. I always feel one, if I come with a group and they leave, sometimes I stay to see who arrives - or I can switch tables in the middle. I like seeing as much as possible, even though that's why I wish for girlfriend sometimes - because I still feel somewhat alone. Maybe because most people don't really understand me. Maybe because I'm the only one that thinks, or so I feel.
