My dad gave my son a very special model car and within the week, it was broken.
Oh no! I hope no one got in trouble! 
He didn't understand, so he wasn't in trouble, but I have to admit I was a little sad about it.
I'd say so. That's so disheartening. I'm sure it was accidental. 
Yes, it was and my dad acted like it was no big deal and just gave him a hug so it was a good lesson in forgiveness.
