I go to the cinema. It's a wonderfully dark room full of strangers where entertainment is shoved at me for about two hours. If I had a problem with people before I came in to the screening then, provided the film is at least half-way decent, I'll probably come out feeling refreshed and ready to face the world.
If, for some reason, I'm not near a cinema or there's nothing good on, I'll probably just go to my room, or maybe have a lil' walk. Walks are really good at clearing my head, but they're definitely not exclusive to me! My room is a sort of sanctuary, but I spend a fair bit of time in it anyway, so its effects as a 'Bat Cave' are less than that of a cinema nowadays. Still, they both have their uses.
