I also write lengthy notes about what happened last night and let the complex manager have them.
With all that went down last night, I was concerned I'd forget something. There was just too much, and it was easier writing it all down.
The office was locked at the time (around 10 this morning), so I just folded the paper and slipped it under the door.
Though I can't be sure, I think the Banging Brood got bad news. At around 2 p.m. today, someone in that apartment slammed the front door twice. But that could have been over anything, really.
