I lived in a duplex off of Shoal Creek my senior year at UT. We had a great little backyard with speakers mounted up in the eaves, a picnic table, and horseshoe pits and always ended up playing whenever we had friends over. My roommate also worked for Red Bull back when they were first getting going and he got a couple of free cases of Red Bull every few weeks as a perk. This meant that our place always ended up as the late night party spot after we were done with whatever debauchery ended at 2 am.
One night we were tossing horseshoes and I'm sure being loud jackasses when this neighbor who I had never spoken a word to after almost a year of living there stuck his head out the window and yelled at me, "Are you guys really playing horseshoes at 3:30 in the morning!?" I was fully engulfed in god knows what all substances and all I could think of to say was, "Is it loud?" He yelled back much louder "My bedroom window is RIGHT HERE!" I just told him we were sorry and we shuffled inside to party some more. When I came to the next day and went outside to survey the mess in the back I noticed that the outdoor speakers were still on blaring whatever was on the TV inside. They were cranked all night. Oops.
That was the only time that dude ever said anything to us after probably 30+ loud nights in that backyard. I'm a grumpy fuck about stuff like that now when I'm on the other end of it and I need to try and remember Mr. Are You Really guy the next time it happens.
