One of my first days in preschool I stepped on a crack and one of my classmates freaked out saying that I just broke my mom's back. When my mom picked me up I apologized profusely but instead of setting me straight she replied, "I was wondering why my back hurt all day." I avoided cracks for years until one day I got mad at my mom and stomped on a crack repeatedly. When it didn't work I assumed that it only worked with some cracks and continued avoiding cracks for an embarrassingly long time.
