flower's heart

This evening we were eating dinner and we made Danielle try an artichoke. Trey was explaining to her that she had just eaten a flower, how it was cut up, etc. I said "the part we ate people call an artichoke heart." Her face fell and she got very upset so I asked her what was wrong...she said "I don't want to eat the flower's heart." Thankfully, Trey saved the day by explaining that the flowers don't have real hearts--the heart just means the center.
