busy possums

this morning a child noticed a nail hammered in (poorly) in a brick wall of a building at work. it's been there for years but he's never noticed it so he decided that last nite some possums must have come and hammered it in. when another child came over and asked how the nail got in there i told him that henry had a pretty good idea. henry told him and as he finished the second child got a big smile on his face like "that couldn't have happened, you're making that up" but he turned to me and said "possums would have accidentally hammered their fingers if they tried to hammer a nail."
when they aren't driving us crazy the kids at work are funny sometimes.
