A plumber had a difficult day at work with various problems that put him behind schedule. On the drive home, he was silent and upset. However, upon arriving at his home, he stopped at a small tree in the yard and touched the branches. When he entered his home, his demeanor completely changed - he was smiling and happily greeting his family. When asked about the tree, the plumber explained that he hangs his troubles from the job on the tree each night so they don't enter his home, and that God helps reduce their number overnight.
