The Serial Smiley-Facer

One day I noticed a smiley face above our apartment number. I asked Eldon if it was him. Nope. Tom? Nope.

Then weeks later I noticed another smiley face! Eli? Nope...

Then when Eli was waiting for me to answer the door one day he drew this:

The running man.

The fingers that drew the smileys remain unknown.
