Have a Blueberry

A 4-year-old was coloring a picture while I was talking to her mother one day last week.  The little girl asked her mom if she could color the glass blue.  Mom replied that there is probably some blue thing to drink.  I said it would likely have blueberry juice in it, and asked the little girl if she knew what blueberries look like.  She said no, so I described them to her, ending by commenting that they are yummy.  She asked me if I had any, and I said, "Yes, at home."  The response:  "You have to give them to me!  It's called sharing."
