Never trust quiet

This morning I was doing some yoga in the living room & May was being extra quiet in the playroom. Now, after 5 1/2 years of parenting, I should know that quiet=trouble but did I listen to myself? No I figured she's 4 for pete's sake how bad could it be? Rookie move. She was using Elmer's glue to put up her new Hello Kitty poster on the playroom wall! And I mean a LOT of glue! AND there was a trail of said glue from the art table to the wall on the carpet! I asked why she used glue and she said she couldn't find the tape - which was right next to the bottle of glue. Suspicious no?
