Since Deepavali (also called Diwali), I have made it a habit to give a bar of chocolate to everyone who delivers food/grocery, etc. The bewildered look when I thank them and hand over the chocolate, the bright smile when they realize it’s for them, to the happiness on their faces as they drive away.
I must confess that I’m doing it for a selfish reason – it makes me feel happy, and I go about my day with a happy smile, knowing that I made someone smile too. That’s Rak both ways, I think.
A smile is meant to be given and you always get one in return.
