We found this in Ella's lunch box.  I'm guessing she was concerned that I'd lecture her about eating dessert before lunch.  Her cookies were not in her lunch box, her fruit was.  Still, the note was so unexpected and funny that I couldn't lecture her, even though she had meticulously chosen this very banana for her lunch.  It's now sitting on the kitchen counter.  I'm planning to give it to her later today, when she has a little more time.
