Who's daughter is this?

So I go to pick up the Shelbs from Preschool today. As she walks out, she has a look on her face similar to the one above. I am looking at her thinking "what the heck is wrong with her?" As I approach her, her teacher comes over and says "she is mad at me?" and I said.. "Shelby, what did you do?" She wouldn't answer....So her teacher proceeded to tell me that Shelby choose not to help clean up today...She got in a little bit of trouble and was not given a sucker because of this , I told her that was what I would expect her to do..I thanked her and we got in the car. As we drove home I tried to explain that when her teacher asks her to do something...She needs to. The only thing that she said to me was "why...My teacher is mean now...." I don't mean to brag or anything, but honestly, the kids have been pretty good. I really have never had to deal with any dicipline problems. I think this little child may just make up for all of them.. I realize this is not that big of a deal.. But this girl has serious potential.. Please, everyone pray for me..
