IS THIS WHAT GETTING OLD MEANS ?

An older couple were lying in bed one night. The husband was falling asleep but the wife was in a romantic mood and wanted to talk. She said: "You used to hold my hand when we were courting."
Wearily he reached across, held her hand for a second and tried to get back to sleep. A few moments later she said: "Then you used to kiss me." Mildly irritated, he reached across, gave her a peck on the cheek and settled down to sleep.

Thirty seconds later she said: "Then you used to bite my neck." Angrily, he threw back the bed clothes and got out of bed. "Where are you going?" she asked.

"To get my teeth!"
