I read the whole thing squirming and expecting to read about the break :/ I'm really relieved that the story has a happy ending.
What I don't understand is why an injury while playing a contact sport like that would be surprising. When you're playing a sport, there is always a chance you will get injured and while some injuries are not that bad, some are truly horrendous and it can really happen to anybody at any level or age.
He was very young and we had never heard anything break that loud.
The idea of child breaking something with such a loud sound truly disturbs me. I'm really glad he turned it around!
