Man behaving badly

I've written this post twice now only to have it mysteriously disappear before I could get it up on the site, so this time I'm cutting to the chase.

I was woken up at 2:30 last night by loud music coming from a neighbor's apartment. I sucked it up and decided that despite it not being the best way to meet the neighbors, I really needed more than an hour's sleep if I was going to get through class the next day without losing consciousness. I went to find the responsible party and rang the appropriate doorbell. I got about three words into "Hi, I'm sorry to be meeting like this, but ..." before I was cut off by,
"Is it too loud?"
No, you nitwit, I generally make social calls on people I've never met at 2:30am while wearing a bathrobe and flipflops.
"Uh, yeah."
"OK."
"Thanks. Sorry." Wait a second, why am I the one apologizing??

In case you're curious, the guy in question appeared to be of the mid-to-late-20s American species. Nice to know that we're now exporting frat/party boys so that the rest of the world can experience that joyous product as well.  (And I did make it through class without falling asleep, but only barely.)
