Did you ever owe anyone money for a mistake you made?

  Yes.

I was thinking for a second on how to answer, relating to the situation, with its rather strange details.

Then I saw Randy D's answer -- much better - -

I walked into my sister's brand new house, opened a slider and the handle broke right off.  I ordered a new one that night and had it sent to her.  My brother-in-law still makes fun of me about that....20 years later. This post was edited by Thriftymaid at September 8, 2019 9:43 PM MDT

No, I can't say as I have.

I paid $800 for one.   I left a sink running and it leaked downstairs to the flat below and caused water damage when I was about 30.  

Yes it was called excessive speed or similar

Yes. I left a truck idling and reached in to turn the key off. It was not in park. It rolled backwards. I tried to hop in but could not in time. I was pregnant and had my infant son with me. I had to get him safe first. It rolled out the driveway through the road into tho the nieghbors yard. I was scared it was headed for their horses in the barn. Thankfully it stopped. It ran into their old swingset. 
I knocked on the door and explained. And told them I would replace the swingset when I was paid Wed. I brought them $100 to replace the swingset. They were happy. I do not know what they spent it on but the swingset was not replaced.
