I asked Ella and Preston to snap the ends off the green beans we were having for dinner last night. While they were working on that, I busied myself with the rest of dinner. I eventually turned around to see how the green beans were going. I saw Preston pick up a green bean and snap the ends off by biting and eating the middle of the green bean. Ella had a nice pile of snapped green beans and Preston had a pile of green bean ends with no middles!
