I'm like whaaaat??? Is it possible they just measured stuff today and will come back tomorrow? Should I call my landlord now or tomorrow? It's hot out and I still feel weird about having my window opened, even though I have the locking things on there.

At the very least can I get a new screen for the side that doesn't have one?

Also, should I put up flyers warning the neighborhood? I'm on the fence about this. I have the case number that I can refer to, like "Breaking and entering is a crime, if you know who wrote this note please contact the police regarding case #[too lazy to find where I wrote it down]"

This person already knows where I live I dunno if I should
