Hey, the way I see it Brat, either I treat myself to a meal or a movie and really be by myself - or spend my fun money listening to bells go off and the chatter of voices And lots of lights with colors - like a party!
I sometimes watch a movie in cinema, alone. But well, when I tell about it at work they think I was there with others, so it was social :p. Same thing with going swimming, to a flea market, shopping or whatever else- I'm amongst people, who cares that I almost don't interact with them.
Well, that's no problem for me.
Often when I come back from work I am quite angry inside and well, the first who meets me will get it... As I know that I want to be alone for an hour or so, I need to, I don't want to hurt anyone who has absolutely nothing to do with it.
