I was sitting in a local food court the other day having lunch when I spied a young toddler with his mother, sitting in his stroller while they were eating lunch. I caught his eye, and proceeded to cover my face with my hands for a moment and then suddenly open them up while delivering a big, smiley "peek-a-boo". He squealed with delight, waiting for me to do it again . . . and again . . . and again. Each time, the laughter was bigger, and the fascination greater as he watched my face disappear and then appear again.
