Me: "On this page, you need to draw a line from the little cat, to his mommy, without touching anything else.
Monkey: "Why he can't touch anything else?"
Me: "Because we don't want him to fall down a hole, or step in a puddle, or trip on a log."
Monkey: "Okay." *Draws his first line* "Veeeeermph! Oops! He broke his leg."
Needless to say, I had him do it again.
