driving home from work today some guy run up my anus.
my boot and everything is fine and there is a slight dent in the rear bumper.

i got all the guys details and when i asked for insurance details he said lets keep insurance out of the equation as the dent is only small. you fix it and ring me with the bill and i will happily pay.

now my question is do i a) report this to the police b) do i ring my insurance company and let them sort it out and c) or do i get the bumper fixed myself and send him the bill..

as im young and have never had any experience in something of this nature any advice or help is greatly appreciated
