which one of these things is not like the other?

The other afternoon I was sitting at my desk doing some work on my computer, when Rose walked up to me and handed me my chapstick. She smiled and said "Daddy, here's your glue". I guess to her it looks a lot like her glue stick that she sometimes uses for crafts. My only concern is that if she sees me one too many times using my chapstick, that she will eventually try it herself and glue her lips together.
