One Perfect Sight

On my way back from school today, I was walking up the hill to reach my apartment. My back was hurting due to my heavy backpack and I started walking slowly ..close to the play ground where kids of the community play. Just when I was passing it, one of the kids playing inside the fenced area, came running.. He had seen his mom park her car behind me. He yelled with the purest delight "mama! mama! mama!". He then talked excitedly about some thing in chinese.. she was answering him with equally loving voice. The boy was pulling the plastic bag she had in her hand to look what she brought for him. And the mom started talking with the grandma of the kid and so on..

But, what I wanted to record is, what I do not want to forget is, when the boy who was sufficiently occupied in playing, turned around and saw his mom, and came running, and was shouting "mama mama" and was eagerly banging the fence with his palms.. I just cannot write down how it felt. The happiness shined through his eyes.. the smile was so pure..and perfect..
This is by far, the happiest face I have seen.
