The insight the toddler gives me.

Today's "It's disturbing the insight my toddler gives on my habits"  experience.

I was reading one of my textbooks while marking with a highlighter.
Andrew was next to me drawing on his papers with his highlighter.

I notice that Andrew has the unopened end of the highlighter stuck in his mouth while grinning widely at me. At which point I realize, my highlighter is in exactly the same position.  Appears I eat my highlighters when studying.
