That awkward moment when... hand your ID to the cashier to prove you are legally able to purchase the rather impressive stock pile of delicious beverages you have just placed on the conveyor belt, and she pulls out a clipboard to write down your birth date.

She does this inaccurately, indicating you were born in '88.

You open your mouth to correct her, and then realize that even if that were your birth year (thus making you two years younger), you would still be plenty old enough to legally purchase alcohol.

Ummm, when I did I get so old?
