Too tough?

At dinner I said in front of everyone: "Jude is my best behaved child right now."  A second later Petra got up and went to her room.  When I went to her room, I asked if she was upset about what I said and she said " I want to be the best," and "I want to be like Jude." Well, we talked about needing to rely on God's grace for anything good and how Petra could improve her reactions to situations where she doesn't get what she wants. I assured her how much we love her.  But I think it's a good thing that she wants to be like Jude. He really is setting a good example right now!
