Unexpected cold snaps had destroyed the buds on a man's peach tree for two years in a row. This spring, he was ready. He replanted the sapling in a large box, mounted it on wheels, and put the tree in the garage whenever the temperature dropped.
One warm April day, the man was wheeling the tree out into the yard, and he stopped to give his dog a drink from the garden hose.
A neighbor watched the scene with amusement. "Frank," he finally commented, "you're the only man I know who walks his tree and waters his dog!"
