Not sure what to do...

Just a quick note about what happened during our writing time. I had the students write about what they would do on a rainy day. I then collected their journals and read them aloud and had the class applauded in different ways after reading them. Long story short, I got to one story that said something like "I would play games and read books. Then I would call my teacher and have a sleepover..." This was written by a girl (the students didn't know that) but I felt like I had to immediately address this and say that my number is unlisted, no student has ever called me, I don't have sleepovers, etc. This just put a little uneasy feeling on me and now I'm wondering if I should make a copy of it and discuss this with my principal just to cover myself. Any thoughts.
