I wasn't the best behaved child in the world. I caused thousands of dollars in damage as a child
Kids can be destructive. What did you do to cause thousands of dollars of damage?
My dad never bought me a mini racing go-kart and I was insanely jealous of my kindergarten friends, but they let me try out their kart and I crashed it.
It is messed up to damage someone elses property, however this is something that could happen by accident. If this did happen however you should do your best to apologize, and do whatever you need to do to make it up to that person.
We're adults now, so maybe they should just get over it?
There's a good chance they have gotten over it, but it's never too late to apologize. I'm sure they'd love to know you regret what happened.
