I don't usually drink enough to get more than an imperceptible buzz, myself (us old folks, you know - now when I was your age . . . mutter . . . rambling story that goes nowhere . . . snore). But tonight seems to call for it.
I'm not sure if you're genuinely excited because you get off so early or sarcastic because you have to be in so early, but either way, have some fun on your birthday!
