Too young or too old?

Last night I was in a store and the woman asked what I was looking for, and if she could help me. I gave her my usual response: “I am just looking.” Unless I cannot find what I think I should be able to find, or I need a different size, I am a leave-me-alone kind of shopper. She then proceeded to ask me if I had any kids and if I was back-to-school shopping. I was a bit shocked about the question (the age for the store would be a tween store). Did she really think I was that old?

While it is completely numerically possible for me to have a tween, and even a kid in college (yikes). I believe it is the first time that I have ever been asked if I was back-to-school shopping for children I do not have. Maybe I was a bit more shocked because just mere weeks ago I was carded while out with work colleagues. When the woman saw how old I was I could see she was shocked. I then asked her how old she thought I was, and she said under 30.

While I should be flattered by her subtracting 6+ years from my life, the entire age thing baffles me. How can one individual think I look much younger than I am, and another potentially assume I have a tween. I know I am stretching the store comment a bit (and I know I had crazy bags under my eyes after a long day and week), but I am perplexed. After getting carded, I could not get over it. Those with me told me it is a compliment and I can see what they mean, but does it also mean that I act younger than I should?

Or, should I just shut up and be grateful that the waitress took years off my life and know that years from now I will look back and want someone to do that for me again?
