Could be a nice neighbor just taking the time to cut your lawn because it didn't look like you had the time.  Don't know why you jump to passive aggressive. My dad and I would cut the nebors lawn if it looked like they haven't in a while just to help

Did you and your dad just go on to other peoples property without permission and start mowing?
