Run that by me again?

Erin and I were in the supermarket other day and the guy at the checkout said the greatest thing ever. I was buying some wine and when he scanned it he looked and up and said "Are you over eighteen?" I was nonplussed for a second before saying "Uh, yeah. I'm 40 in six weeks".

I know I look younger than I am - people usually take me for about ten years younger - but this was totally new. Excellent!
