I'm Just like Who?

Last Saturday, I was "encouraging" the kids to clean their room. When they would stop and dally or try out a marker to see what color it writes, I would say to them, "Come on, keep picking up. You have to get your room clean today." After about three or four time of telling this, Ethan grumbled, "You are just like Pharaoh, always telling God's people to keep working." While I am glad to see that he is listening in Sunday School, I'm not so sure I like the way he is applying it!
