A man and a woman are driving down the highway when another car passes them. The woman notices the occupants of the other car are young and obviously in love. The girl is sitting very close to her boyfriend as they cruise on down the highway.
This causes the woman to think back when she and her husband were young and in love, and wondering where the show of affection had disappeared to over the years.
Finally she says to her husband, "Remember when we used to be like that young couple? Where did the love go, honey?"
Her question was met with a few moments of silence. Then he quietly replied, "I haven't moved."
