I'm 24 and look 30 something, and I get that all the time...thank you cigarettes!

I have the same issues. I must look younger than I am, too. My daughters are 23 and 18 and when we are out and about, we are always guessed as sisters, too.
I went to enrollment conferences with my daughter recently and they said, "Umm, I am sorry Miss, but we can only release this information to parents."...LOL It took another teacher to tell this one that I was her mom!
Yep, I get carded, too.

Most of the time, I just laugh it off. But, sometimes it does tend to get under your skin a little bit - especially about the fact that you are prejudged on what your age and maturity levels are just by someone looking at you and it takes time and energy to convince them otherwise when you are trying to take care of important business.

So...I can relate...sigh.

If i get carded uhhhhh ya i need a card thats right my dog had it for lunch...
