We had just finished lunch. S and I were taking a walk within the company campus. The weather was warm but not too sunny and it was just right for a walk.
There was construction work going on ahead of us. We saw that one of the workers was just unpacking his lunch. As we got closer, he said something to us (in Marathi) with a happy smile. I did not know enough Marathi to understand him. I found his warm smile unusual for he had not met us before. Marathi-knowing S replied to him. I asked S what it was about. S told me that he was inviting us to share his lunch. (S had replied that we had already had our lunch and thanked him for the invitation.)
S said that this is a custom followed when anyone comes by when you are having lunch.
I had heard of this custom but had never witnessed it before. That too between total strangers. It's nice to know such things still exist! :-)
