Dear Mr. Whoever-the-Hells-You-Are,
We couldn't help but notice that the door that was not there, but then was, is now gone again, replaced by this rubble between us, since you can't seem to hear us through the rubble, perhaps you can throw this back with a reply to our questions:
1.) Who are you? 2.) What are you doing in this hiding place of ours? 3.) Who put the door in? 4.) Who blasted the door down? 5.) And since you probably don't want to leave, perhaps an arrangement can be made? 6.) What are you doing in here to begtin with?
Sorry if this paper glided into your head...
-Izzy
