Sarah is sitting on a bench and is crying.She is crying because she did not get what she wants.She does not yet understand she doesn't get everything she wants.
John asks Sarah why she's crying on a bench.She says it's because her parents suck and did not give her what she wants.John asks if she could be more specific about her issue.
She tells him it's because her parents got her a green Lamborghini instead of a pink one.He tells her that he really understands and sometimes parents can really suck
He says "I know what you mean, my mom and dad did something similar when I asked for a blue Bugatti and they got me a green one instead I was also mad".
Later on that day He saw an ad that was about donating to children who need money for shoes and he thought about how he was privileged and how dumb the stuff that he complains about is.After that point in his life he tried to be more appreciative of what he had and to always look on the bright side of things.
Sarah stopped crying, understood, and agreed with his point and from that they forward she always tried to look on the bright side of things and be more appreciative of everything
