In third year university, I rented the basement of a family home. The woman had her Masters degree in Early Childhood Education. She also had a three-year-old son and a new born. During the day, she took care of other children in the neighbourhood.
As I went upstairs one day to use the bathroom, I saw Evan (the three-year old) and a neighbourhood girl (about two years old) standing around the toilet with their pants around their ankles. I overheard him say, “Watch. This is how I do it.” Followed by a few seconds silence. Then I heard him state matter of factly, “Oh. Maybe when you get to be my age, you’ll grow one. It’ll be easier!”
