Thanks to this thread, I would definitely be more aware. This kind of reminded me about something today..

Today I was in my backyard and I was getting my dog inside and these guys who were in the neighborhood cleaning up the tree branches and stuff and right when I was making my dog go inside two of the men were looking at me over my wall and trying to tell me something or talk to me but I looked away and went inside. I found it kinda creepy, like you don't talk to people in their backyard over their wall. You just don't do that lol.
