The Clashing perspective within a frame!

At what point of time in life did your realized that people might have different perspective than yours and that's completely "OKAY"!
I just came across a picture on instagram's page which I follow since long, and I wanted to share that picture here-

This picture just bought instant deep feelings of realizations within me of being positive , negative and clashing perspective.
The tree shedding flowers and beneath are people expressing their intake of the situation- The left couple being happy and joyous enjoying the flower rain and spreading positivity and the left old lady was irritated and disturbed through the falling flowers and spreading negative vibes but if we see thoroughly I feel like because there's reason for the lady as she needs to clean the floor up.
But yeah that could be concluded into different perspective towards a single situation. which is a known fact but still didn't deeply accepted.
