HE DOESNT WEAR HIS RING?

Ladies how would you respond if your husband came home without his ring on? My girlfriend was telling yesterday that her husband walked in the house half way tipsy and she noticed his ring wasn't on his finger. She said she didn't question him because he had been drinking. She said she went out to his car to get his lunch box and found a pink hair band in the back seat. When she asked him this morning he said it was their daughters Kay, she told him she never bought Kay any head bands because she was too much of a tom boy. ANY SUGGESTIONS???!
