What would you do?

What do you do when a solicitor or some such person comes unexpectedly to your door?

I always try to be as nice as I possibly can to anybody who shows up at my house, be they friend or... random person (of course I'm careful and safe too) but hey, door-to-door salespeople are humans just as much as I am, and deserve human decency and kindness just as much as anyone else.

Today, though, oh today, I got home from a lunch date and laid down on the couch for a moment, and the longer I laid there, the more I felt I could not be prevailed upon to do anything else for the rest of the day (don't worry - I did eventually get some things accomplished).

I've been having some pretty bad tension in my neck off and on since New Year's, and it returned in full force today, so I got myself a book and settled in - curled up under the warmest afghan in the house, by the fire and the Christmas Tree. I felt perfectly cozy.

Then came the knock at the door.

I propped myself up on my elbow and looked out the window of the front door.  I couldn't really see a person, but I saw a clipboard with some colorful pamphlets on it, and assumed there was probably a person carrying it.

My couch is situated in just such a way that if I'm lying on it, you can't see me from outside the house, so I just stayed right where I was because I did. not. want. to. move.

But y'all, I felt bad about it - it's the silliest thing, but I really felt sorry that I didn't answer the door for that poor person, from whom I certainly wasn't going to buy anything anyway.

This is my house, for goodness' sake, and my front door, and I can choose to open it or not as I so please, but I still feel a deep sense of obligation to open it to everyone who happens to knock.

So, what do you do?
I actually want to know if I'm the only person who feels this way.
