My earliest memory is of me and my little sister getting into trouble. I was four, she was three. We were playing in the yard of the building our family lived at the time and found a piece of chalk. What does one do with chalk at that age? We drew lines on the walls. My mother still occasionally brings up how quick-witted she was when she outsmarted my three-year-old sister to give up the truth after I had managed to dodge it. Then I remind her of how she felt compelled to go and wash something off the wall rain would have taken care of anyhow.
