Dear Sky,

Thank you so much for lending me your bike several days ago. However, today I am writing to apologize for accidentally breaking it yesterday.

I was supposed to leave my bike in a parking space, but I mistakenly thought it would be fine to park on the side of the road for a few minutes. Unfortunately, a car accidentally hit it and broke its seat. Immediately after that, I went to a nearby bike shop and changed my seat. Anyway, I’d like to say I’m disappointed that I was so careless.

If you have any other requests, please feel free to let me know. I will do my best to make up for my mistakes.

Yours sincerely,

Li Ming
