What is evening ? Very ridiculous question but the answer is very beautiful . 

Evening, When the sun is going home.
When the birds are returning home.
When people are returning home from work. When the farmer is returning from his fields with his cattle.

Birds chirping  People smiling  and waiting.

You thought it was just my imagination but it is not imagined  . it is 100% real that any moment in this life depends on you how you ever feel when you are on the roof of your house . Also sit and watch, look around. There are many changes in the environment
