Start small: pick 1–2 familiar faces you encounter regularly - a neighbour, colleague in the lift, fellow commuter, building/security staff, shopkeeper.
Ask and share: ask their name and preferred way to be addressed (e.g., Ramesh ji, Akka, first name). Share yours too.
Use and add warmth: next time, greet them by name and add one friendly line (“Good morning, Ramesh ji. How’s your day going?”).
At your next touchpoint, simply add their name to your hello
Use the same courtesy for everyone, regardless of role. Mirror pronunciation and preferred address.
