Is it normal to drink by yourself in a bar and avoid people?
it's a bit of a paradox. i hate most people who hang out in bars as i find them obnoxious but i enjoy getting drunk in a bar and being extremely anti social while surrounding myself with said people. i also make it a habit to reject most people who attempt to make conversation, including good looking women (i derive a great sense of pleasure of blatantly rejecting women despite the fact that i like to have sex with them).
at the very least i don't do this all the time just nights when i'm in a particularly bad mood. for various reasons i'm not exactly a social butterfly even while drinking.
