The sticker games
This game can be hazardous. What made the technician place the yearly maintenance sticker way down below? They are meant to be in line, one underneath the other. This way, every time someone passes near the boiler, his heart will stop just for a second until he notices the 2014 sticker on the bottom of the boiler.

It will also make the homeowner question the expertise of a person who did the maintenance. The man can’t tell up from down, for crying out loud.
