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 held up on my way back．Just before I turned corner of Park Street, I happened to seeing an accident．A little girl was hurt and his 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 right．When I got back, it were already 6 pm. I hope you understand．
Thank you!
Li Ling
