I just have to ask

I am in highschool but look much younger than I am. I was glad when I finally got to highschool, because I thought, hey, here the youngest I could be is 14 (I know people skip grades but generally speaking). Now anyone who sees me at school knows that I'm at least a freshman (which I am)

I was getting lunch today and in the nacho line. I'm up, and say to the lunch lady "chicken please" with a smile.

She takes a second just looking at me and says, "I just have to ask, how old are you?"

I say "I'm 14."

She kind of squints the way you do when you're trying to picture something in your head, and she says to herself "14...14..." I was just kind of staring at her, and finally she starts putting the meat in my bowl and says something like "sorry, I just had to ask..."
