On a trip to Disney World in Florida, my husband and I and our two children devoted¹ ourselves wholeheartedly（全心全意地） to the wonders of this attraction. After three exhausting days, we headed for home.

As we drove away, our son waved and said, "Good-by, Mickey."

Our daughter waved and said, "Good-by, Minnie."

My husband waved, rather weakly, and said, "Good-by, Money."
