I explain to the doorman that I'm ID-free, tell him how old I am, apologize, and smile at him. He is *immediately* belligerent, genuinely grade-A disproportionately pissed off, as though I've done this to him on purpose and it's caused him great harm. "What year were you born?"
"1976," still smiling.
"How old are you??"
Uh. "Still 30."
"When did you turn 30???"
"July of 2006. I was born in July of 1976."
"You need ID!! What would you do if the cops stopped you on the street and demanded your ID? How would you prove who you are??"
Now I'm not smiling anymore. "Okay, when would the cops stop me in the street and demand my ID? They can't actually do that."
God knows who he's talking to at this point. "See, she's borderline. I can't tell how old she is."
I try smiling again. "Well, that's very flattering."
"It's not flattering if I don't let you in."
"No, it's still flattering, I just wouldn't get to see the show. Please, ask me anything." Here, I'm expecting 'when did you graduate high school' or 'who ran for president in '84' or anything intelligent, but instead:
"How old are you??"
"30."
"Fine, go in. But I'm not stamping your hand."
