I finally managed to anticipate one of Clem's compulsive (and strongly discouraged) jumps into the branches of our fake Christmas tree. Usually he will jump into the tree, I'll grab the camera, and then he'll jump out before I can focus on the rascal. He knows we don't want him rappelling the tree, but this of course has nothing to do with it.
We have forgone ornaments this year, as they would all be on the floor, and we regularly find the angel rolling her way down the tree by the time we get home each night. Sigh.
