Out of the mouths of babes

Last Friday my students were using ipads to reinforce their math skills. Sadly I was two ipads short and so, quickly going to solution, I asked the two students go to the computers and log onto my school website so they could play some math games. I didn't hear all the conversation at a nearby table but the final comment was, "Yes she used to be a teacher." Did they think that anyone having so much fun with them this year couldn't be a teacher OR did they somehow know I was going to turn in my retirement papers today!!!?
