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 immediate I used it.And I was hold up on my way back.A little boy was taking the corner while a truck cut in.He got injured and needed timely help. So I helped rush him to the nearest hospital.I stayed here for one and a half hour and made sure that the boy were all right.I got back very late.Still I think it worthwhile.I wish you can understand.
Thankyou!
