An Apple a Day

You might think that David had heard the expression, "An apple a day keeps the doctor away" because almost every time we go grocery shopping, he insists on picking an apple. It is always a red apple, his favorite color, and he carries it through the store until we pay for it. He has no intention of eating it; he doesn't like apples or at least refuses to try them to find out whether or not he likes them. Instead, he will carry it around for several days, occasionally touching it to his upper lip to either feel it or smell it. He will carry it around until it gets bruises and soft spots from accidentally being bounced off of the floor, or rolling under the car in the garage and then I throw it away and we buy a new one. It is a waste of an apple, I know, but it does make the shopping experience easier. Do you suppose that David realizes you have to actually eat the apple to keep the doctor away?
