look teenager

Ms.P from our office often says "You look like a teenager." to me. Yes, I am short and small. And I don't wear formal clothes in most of the time. Today, she came to me and said so again. It is OK, she is not the only one person saying so. I was told the same phrase from my daughter's friend. Anyway, then I replied "Oh yeah? You know, I bought a hair straitner." Then she goes "My daughter has that one." (Her daughter is a TEENAGER.) Oh well. We had a nice chat about hair styling after that.
