See, the sad thing is that I don't know that I've got one anymore - so there's nothing I can really defend, since I no longer smoke, I drink rarely, don't do drugs, and I'm not a whore.

There's always tea.

So, if that's my only vice, then I defend it by saying that a) it's delicious, b) it makes you feel good when you don't feel good, and c) it's got caffeine. Who can say no to caffeine?
