As I'd rather suspected might be the case, everyone at school thinks I look super young (thank heavens I work in an elementary school and not a high school).
The custodians at both schools love to tease me about being nineteen. One mom told me her daughter came home the first month of school and said, "The new librarian must be REALLY smart to have finished college while she's still in high school."
On the other hand, I started to wonder if all my commuting into the sun both ways was starting to take a toll on me (hello, squinting), when a second grader asked how old I was last week. I asked her what her guess was and she stared at me a while and then said, "Forty?"
Hmm, time to break out the anti-aging cream, I think.
