Aged Wine

I went to the grocery store this evening to buy myself a bottle of wine and at checkout, the woman asked for my ID! I told her, "I have underwear old enough to drink". She just looked at me and blinked. Kids - no sense of humor. How do you react to being carded if you're pushing 40? I'm too old to chalk it up anything but momentary insanity or pure blindness. But too young to say, "bless you, child!".
