Oblivious Realization - 2

It has been nearly five years since I wrote about them. The father, the mother, and the daughter who spoke Kannada. Their regular presence on the street next to my house has been my regular observational ritual. It's as if nothing has changed in the last ten  years. However, in the last few months I didn't see them for very long. I thought it's strange since they were like people who would disappear from that locality only upon their death. Their presence has made my presence on that street ancient. I wondered if one of them would be permanently missing when I see them next time. The other day, I saw only the mother and daughter(as I'd identified them). But nowadays I don't see them regularly. Will I again become new to that street as they fade away?
