Why

can't he just take it as a nice gesture and live with it?

So, one of our neighbors has a snow blower, and he went over the sidewalk in front of our house.
My dad starts bitching about how "Oh, it's on the curb" and "it was fine before"

Why can't he just DROP IT, take it as something he did out of the kindness of his heart, AND LEAVE.
GAH.
