Carrots help you see better

We had carrots with our dinner tonight.  McGuire was devouring them, however Kennedy was a little more reluctant to eat hers.  When I said to McGuire, "You are going to be able to see really well because carrots help you see better."  Kennedy said, "Carrots help you see better?" and she popped a carrot in her mouth and immediately covered one eye with her hand.  She then said, "I only ate one carrot so I guess I can only see out of one eye."  She was quite happy to eat one more carrot just so she could see out of both eyes!
