The intensity of happiness may vary from person to person...

Rich dad gifted his daughter a super expensive mansion.
Poor father brought his daughter a 2nd hand laptop as she was struggling for one at her school.
We live in a world with multiple worlds insides, mixed and different feelings and meanings of the same word happiness.
I just wish all the worlds should meet their level of happiness, sometimes what is a dream for us may not be for others, but that cannot define our happiness.
