should have a sign made up just for people like them to put on door “Don’t bother knocking, I’m ignoring you”
I used to have a “NO SALES, NO SOLICITING, NO RELIGION” sign taped to the window glass of my front door when I lived in the city.
My next door neighbor knew my sentiments and would discourage those people from coming over if they got to his house first.
Oh, I intend to answer my door if they knock.
Provided they actually make it past my mean pitbull...
