Heโ€™d always held a deep affection for the sycamore, a tree he had planted as a child. He approached the house he grew up in with a skipping pace, barely able to contain his glee. He felt a light, airy feeling in his stomach as he got closer. This morning, he felt particularly alive. The sight that greeted him upon arrival, however, was not what he expected. It was just a stump, the tree having been removed.

He burst into fits of giggles. The situation struck him as hilarious. He began to do a series of playful leaps and hops around the empty space, muttering, "This is just too good! Too perfect!" He began to create a silly little dance for himself.
