I don't really remember when I exactly started thanking, appreciating or apologizing whenever needed irrespective of my relationship with that particular individual. I think i have incited this in my brother too. I thank. I appreciate. I tell sorry. I think this must be a norm. I thank even my mother even when she gets me a glass of water. I thank the auto driver too. Many a times the word thank you might mean so much more to someone even if it seems like a simple word for us. I always feel, smile is the biggest token of appreciation. Have you...
