I don't drink because I can't afford it, I haven't found something I like, and I don't see much of a point to it. Kids these days think it's cool to get drunk, I don't. Older people like to sip a good alcohol, but all the "good" stuff just smells like paint thinner to me, and tastes awful.
If I found something I liked, and could afford it, then I'd probably drink socially. But I'd never drink to get drunk. However, since other things are taking my money, and I haven't found anything I like, I don't drink.
