Yesterday while travelling I saw a girl carrying a young boy over her back. She was carrying him for some time and then letting him down, again after around 5-10 seconds she would carry him. She might definitely be his elder sister, I could make out from the way the boy was clinging' on her back. This moment was so special & pure. I could see such joy in both of their eyes, they were probably going to the shop nearby. When they reached the shop boy bought a packet of chips and both were having it one by one smiling, giggling, and enjoying the moment. It was such a small and tiny moment but both were so happy. Their giggles and smiles definitely put a smile on my face. And the entire way while coming back I was thinking. What if that young boy would have thought " ohh I am such a pain, because of my injury my sister had to carry me, I am such a nuisance, oh lord, I may be eating her valuable study time, she could have done some important work...
