Do you post in a thread when somebody bumps/necros?
Do you? .__.
Of course I do! That's the fucking point of the Internet.
On topic, I usually don't answer the door, since I live in an apartment building where anybody I know would already have called me or told me before hand that they'd visit me, since they need to be let through the front door. The only ones who'd ever knock on the door are sellers, evangelists or my neighbors.
Yep. I figure since they're out there walking around, may as well hear what they have to say. And if they try anything funny, I've got my tee-ball bat from 15 years ago ready for action next to the door.
