I do not answer the door for anyone that I wasn't already expecting(like a repairman or something). And everyone I know that would be coming to hang out(family or friends) would park on the gravel drive that runs alongside my property, enter the side gate(which is hard to unlock, basically only people I've shown know how to do it), and knock at the back door. So basically, if I'm not expecting someone, and my front door is being knocked upon, I'm not answering. I'll look out the peephole to make sure it's not a neighbor with some emergency or something, and then go right back to whatever it was I'm doing.

I don't like strangers. Go away.
