Hello Prashant

How is Bangalore treating you? Do you continue to be in the same company?

I wanted to check if you are around on September 10, 2023? I am coming there for an official visit on Sep 9 and would like to drop by your house in the evening of sept 10.

If that is not feasible, I may have to come back in October. Are you around on oct 10? or oct. 11?

Do let me know.
