I was in a very pleasant society in pune, maharashtra for 20 days. I decided to morning walk everyday and greet every person I see. An uncle, aunt, girl, boy, people with their headphones on.

Long story short, today greet anyone you meet, the result will be tremendous. A smile on everyone's face, good morning to you. The thing you'll learn is humility, kindness.

It has been proven that the part of brain which deals with greetings also deals with happiness. So astonishing. How easy it is to make someone happy.
