And this morning I was awakened by another knock at the door. (Like I can sleep with all the home improvement racket, and the guy using a leaf blower at 7:30!) It was young woman asking if they could use the phone. I let them use my ancient flip phone I keep around as a backup. Pretty sure there's a connection to last night. My night visitor left when the police showed up, but it was hard to see if he actually left in their custody.

It almost sounds like she used the need to make a phone call as an excuse to case the joint.
