Hi,Susan

I’m sorry that I wasn’t able to return to your bike on time yesterday. I mean to give it back to you before four in the afternoon，and I was hold up on my way back. Just before I turned corner of park street. I happened to see an accident. A little girl was hurt and mother needed help. So I helped them going to the nearest hospital. I stayed here for one and a half hour and made sure that the girl was all right.When I got back, it were already 6 pm. I hope you understand.

Thank you!
