Strange Evidence

Strange things were showing up the other night which are difficult to make an accounting. The first item was a small piece of scratch paper which was lying on the floor. Idris brought it to my attention: "What's that?" he asked and pointed at it. It featured some stickman- like drawings complimented with various, suspicious abstractions in the background not unlike a drawing Idris himself may have made. "Who do you think put that there?" Idris asked. Then he led me to a more provocative item in the other room. A door, slightly ajar, had rubber bands stretched from one doorknob to the other. "Who do you think did that?" Idris asked me.
"I just don't know who would do such a thing" I agreed.
Idris was also able to point out a couple bottles which were banded together and explained his utter mystification at the phenomenon.
We agreed it was very mysterious.
