skin or robot?

William: Mommy are you made of skin? Are you made all of skin or a robot.
Mommy: I am made of skin.
William: Are you sure? Are you really sure?

Thus was our conversation on the way to school one day this week.  William was very serious in his questioning, with a little bit of fear in his eyes.  Ny initial chuckle at his question became realization that I needed to answer him seriously.  I asked if he had watched something with robots under skin, and William said he had watched super hero shows with Daddy and that it scared him.  He decided he should not watch those shows so he can forget about the robots and the bad guys.  I think that is a good idea.
