Why Do You Take Out Your Wallet?

A guy was in a bar drinking beer. He would finish his beer, pull out his wallet and look at a picture of his wife, keep it inside, order another beer, take out his wallet, and look at a picture of his wife.
He did this several times.
Finally, the bartender asks, “After you finish a beer, why do you take out your wallet and look at a picture of your wife?”
The guy says, “As soon as she starts looking better to me, I go home.”
