Also, if you were going to a restaurant, and she was going to be an hour late, what the fuck?
Does it take an hour to eat anything at all, ever? The only time it has ever taken me a full hour to eat at any restaurant is when the waiter/kitchen is glacially slow. I guess you were going out for drinks, and that takes longer, but an hour late? Really?
If I was going to be an hour late doing something, I'd say something like, "No, I can't go, I have this other thing I've gotta do, and it won't be done until <an hour after the start time>, like, maybe. Could even take longer." And then, if the inviters say, "Oh, you gotta come! Just go ahead and come when you get done, we'll see you there!", THEN it's ok, and otherwise I'm just not going. Not, "I'll be there, but I'm going to be an hour late, and could you totally stay frozen until I get there? After all, I am the Royal Magistrate of the Fucking Universe and all."
And, it truly is the height of selfishness to expect a ride to go get her ID. What can you do, in this world, WITHOUT an ID, that she happened to be doing, that she wouldn't have it on her anyway? If she's old enough to drink, she's old enough to drive, and you have to have your license on you at all times when driving. Whafuck?
Tell her I said, "Come over here, so I can kill you."
