I've worked with cancer patients and those talking about 'getting over' these types of things, are oblivious. Until you've experienced it, you'll never know because logic doesn't apply with such strong emotions. My friend lost his first child, he was alive for less than an hour. He has kids now but 10 years after that loss, he cries for his son. Just be happy that it hasn't happened to you.
Ronaldo's tears when Portugal were eliminated, was that for his deceased child too? Nobody knows but him. Messi's live outburst against the Dutch was a bigger issue given the kids that idolise him, but yeah, kick Ronaldo because he's vulnerable.
