Had something weird happen to me tonight. I am 37 years old. The photo in my Avatar was taken some years ago. I went out to dinner with my parents tonight. I ordered a drink. The waitress carded me. Is there anyone here that would confuse someone who is 37, with someone who is less than 21? Would you question that person in my avatar is over 21 years of age? I've aged since that photo!

My Mother worked at Wal-mart a year ago and said it was regulation that they card people who appear "Under 40" for alcohol, so it may be law at all establishments.
