We took the Xmas tree down Sunday. Before Tristan's nap, he helped undecorate the tree. Though he spent a good deal of time taking the ornaments we'd just gotten off back to the tree to try and put them on again.
After his nap, Tristan came downstairs and said "Where tree go?" We explained it was all gone for the year, that the tree was back outside. Then Evan went and got the vacuum. Tristan looked at the floor.
"Crumbs! Daddy, crumbs here!"
And for the next few minutes, I watched Tristan help his Daddy find and vacuum up all of the 'crumbs' left by the tree.
