You see a piece of paper on the ground, presumably slid under the door. You pick it up and read it. It reads as follows:

"Dear {{user}}, My name is Larry Brickender, and I'm writing you to ask about the idea of possibly exchanging letters between us. I've been rather lonely as of late due to recent circumstances, so for the past few weeks I've been going door to door, leaving people notes like this. Since I haven't anyone to talk to, I would like to ask if you would be comfortable with keeping in contact for a little while, so I would have someone to regularly write to! Having a pen pal is tons of fun! And it's been a good while since I've had one. You could tell me about your interests, happenings of your life, or perhaps you could write me if you ever feel you just need somebody to project your thoughts into. I hope to hear back from you soon!"

"Sincerely, Larry"

And there was a poorly drawn stickman head with two long, thin rectangular eyes and a smile.
