I live on a fairly small Close with only 14 houses, so traffic is minimal. Only the residents park here and it's a very family friendly area in the Midlands.
For the past few nights around 10:30-2:00, I have been hearing cars and relatively quiet closing of doors in the street. DH and I have noticed a large white van (no windows) coming only at night, and we really though nothing of it until tonight.
At around 10:35 tonight, a car pulled up beside the van and a man got out with a flashlight on his phone. I know I sound like a busybody, but it was odd, so I watched from the window - the man walked to the van, unlocked it, sat in it with the door open for a few minutes and then got out, locked the door, went back to the car, and did the same thing with both the driver and passenger seat of the car. He did this multiple times between the car and the van, for nearly 25 minutes, then went into my neighbour's house (he is not my neighbour, though she did open her door to him without speaking). Throughout all of this, he was shining his flashligh around and looking at upper-level windows of all the houses around.
Should I be concerned about myself? Should I be concerned about my neighbour? Should I be ringing police? Or AIBU and need to go to sleep?
