As a child, I saw my Dad sit there in the living room in plain sight and NOT answer the door as a church-salesman knocked. He said "it's my door, I don't have to answer it." Changed my life. \n\nIf I have the luxury of seeing them coming and know what they're after, I'll just sit there and give no fucks while they wear down their knuckles after having climbed my mountainous front yard/steps.\n\nCan't imagine if they just waltzed in, though. What a dumbass.
