Someone just spammed knocked on the door and rang the doorbell. I'm alone today and was too scared to go look. It wasn't maintenance or police because they would announce themselves. And we have a no solicitor sign and a video surveillance sign in the window. I think it's my sister harassing us again. Maybe someone trying to serve us? I don't know though. We didn't give our address to anyone, not even the DMV. It's really scary. They did this to H a couple weeks ago, too.
