That's Not Where That Belongs

When I looked out my bathroom window yesterday afternoon and saw a piece of furniture on my roof, a wooden stool, I instantly knew this was due to the fact that we have a nineteen-year-old man-child living in our house-- our youngest son Ian-- and so I texted him to find out exactly why this wooden stool was perched on our roof and he said wasps were coming into his room and he was looking for the nest . . . but I wonder if he was taking our "no smoking of any kind or any substance in the house" rule rather literally-- although he insists that is not the case (but would you trust a nineteen-year-old-man-child?)
