Why do people think it's ok to be sober?

I mean like, alcoholics who get themselves sober, and won't drink

I don't get it.. like, dont people know it's ok to have a drink every once in a while, obviously you shouldn't drown yourself in it, and become an alcoholic but, to just not drink at all, seems ridic to me

and this is coming from someone who once wouldn't touch the stuff, themselves
