Instead of Orders, Offer Choices

Discipline must be exacted quickly to be effective. I have now established myself as the serious lady neighbor.
Last night the new neighbors--or possibly merely the Winter-Dormant neighbors are in mid-party on the patio we share. Three floors up I argue with myself about whether to say anything. Since the party isn't outside Nicki's window, she goes to sleep.
11 pm approaches. Sure, we're Uptown Girls, digging the nightlife (during the summer, when we don't have to wake up for work). We're also digging the open windows since we don't "have" air conditioning and thusly suffer the consequences of everyone else's late nights. But a Thursday? We finished college three years ago. (We are clearly still very young. (But not as young as the kid who got suspended today for "drinking carton after carton of milk until [he] vomited in the cafeteria."))
I'm not going change out of my pajamas so I passive-aggressively call out my window, "Could you keep it down?" I want to add "out there" and "please," but I can't get the words out before someone yells back, "No!"
"Super. Thanks."
Following a few "Dude, your neighbor is pissed" and "she didn't say please" snarks, the party breaks up. No fists thrown; no police or landlords called. An empty victory. So next time I'll try the aggressive-aggressive approach.
