New wallpaper

As I walk down the hallway, I notice blue construction paper cutouts on the wall outside the boy's room. I inquire as to how they are staying on the wall in an oh so patient manner. My actual words, "I know those aren't glued to the wall...." (As I had seen the glue stick in his hand earlier at the table....). His response, "Yep."

I don't think so.....
