I always smiled as a kid then someone said what's wrong with you why are you always smiling?

You let some jerk kid steal your beautiful smile. Why would you do that?

I used to smile randomly a lot until one day, I was smiling at a homeless woman who was doing a very hard work then suddenly she stared at me and asked if I was crazy for smiling at her

It is terrible how an unkind remark like that can change a person and leave scars. It is over. That person doesn't matter. You can smile again.

So their question became the reason you stopped smiling ?

No way... keep smiling.. just ignore who dont see the good things about it.

The same case was when I was the funny kid in school; my teacher said "why are you trying to be funny?", so i stopped and all of a sudden no one liked me anymore :)

Same!!
