I understand your feelings of embarrassment, but someday you might very well count it as a blessing, being asked for I.D..
I was 38 and buying a craft beer for my new boyfriend. I was asked for I.D., and I was thrilled! And the woman in line behind me gave me a thumbs up, and a cheeky smile! And I had a funny little tale to tell when I arrived at his place.
May you be blessed with youthful good looks for a very long time, LL.
