All problems are real
It's easy to look at the 3-year-old who's having a tantrum because his fingerprinting got ruined and think: get some real problems! This is exactly how the fifth-grader going through her first heartbreak views him.
But the fifth-grader's father who just lost his job views her the same way. And those who were unlucky enough to be born in a country with no freedom, where they could be killed for expressing their views, would probably trade a limb to have these "problems". And on and on it goes.
There's no point in comparing, because to each person, their "crisis" is justified and very real. Life and its challenges are not part of a competition. Knowing this should be the basis for compassion.
