X and I were at Ben Parker Elementary, where we go every Saturday for the farmer's market. He likes to play on these climbing structures behind the school. Last Saturday, we noticed some guys climbing in the trees and shaking the limbs. X asked me what they were doing, and I told him the truth: I had no idea. We didn't figure it out until the guys brought me an avocado. X had been playing on that avocado tree for years, and I didn't know what it grew! The avocado, by the way, was delicious.
