Keep smiling in the morning and wishing a good day ahead to completely unknown people as I go to fetch milk from outside the campus and then in the evening I go for a comfortable walk and continue my morning activity.

While most people respond back with a smile and wish the same for me, some are puzzled when I wish them a good morning or evening and ask me who I am, I smile and ask them, "I don't know you Sir/Madam, just wished you." And I smile.

And some even take it as ridiculous on my part to wish them but they still make a funny puzzled/frustrated face to silently move away.
