When I was in 1st grade, our art teacher, Mr. Osama who was also our substitute teacher, used to draw a character on the board named "El tabasheera el sha2ya" or the naughty Chalk. I still remember how I used to love listening to stories about her and how I always looked forward to Mr. Osama's class. Even when we grew up and Mr. Osama no longer taught us, I used to run to him and ask him about his naughty chalk. I wanted the Sunday school kids to experience the same good memo
