Obama says it was a memorable day when they first had preschool children at the White House Kitchen Garden for harvesting. "Two of the little girls were so excited to be part of the harvest that they didn't just pull the peppers off the plants," she wrote. "They pulled out the entire pepper plant. They didn't just pull off an herb stem; they pulled the whole herb out of the ground, roots and all. At first we tried to stop them, but those two were so focused and engaged that we just laughed and let them have at it."
