What's she trying to say???

One afternoon a few weeks back (before Christmas), Josh and I were talking in our bathroom with the door locked (so little kids would leave us a lone and let us talk).  Catalina had something VERY important to show us from school.  And she kept pounding on the door for us to come out.  Finally she gave up and just slipped the paper uner the door (briefly) for us to see...

She told us if we wanted to see it again we would have to come out...  I'm not sure what she was trying to tell us!!!
