When I was five years old some lady said hello to me in the grocery store. I was scared of strangers and hid behind my mother. Turns out she was my Kindergarten teacher and I'd seen her five days a week for the past seven months. I just didn't know who she was without the chalkboard behind her. If you'd stuck a chalkboard behind any lady with short gray hair and a shrill voice, I probably would have assumed it was my teacher.
