Vinay came into my cabin happily, to watch his favorite video. He did this everyday during lunch time. For him, that day was no different. But for me, it was very different. It was his last day at school. Goodbyes are always difficult. I had tears streaming down my cheeks. I looked around frantically for a tissue. But Vinay did not notice anything. Not my tears, not my feelings. He was 10 at that time. I remember thinking, “I taught him everything, but what did I really teach him?”
