On a trip to Disney World in Florida, my husband and I and our two children devoted 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."
