I'm Not Sleepy, Grandma

It is time for grandson to take a nap, but he is not sleepy. At least that is what he keeps telling Grandma. He is trying to think of anything to get out of taking a nap. If he can convince Grandma that he doesn't need a nap, then he and Grandma can keep playing. Grandma, however, has other plans in mind, and she is a patient woman. The more that grandson tries to stay awake the sleepier he gets. So he changes his strategy and starts to think of what would be good for Grandma. Will he be able to stay awake? Or will he convince Grandma that he doesn't need a nap?
