Every Wednesday my friend visits me.Last Wednesday as my friend was leaving a new neighbour came out of their house and told my friend that she had crashed into their car the other day.My friend was shocked as she had no knowledge of any impact but panicked and said I did not know I hit your car but will pay for any damage. My friend then said I come every Wednesday so the neighbour said well it must have been Wednesday. The problem my friend now has is that she has no recollection of any impact, the women said the other day and then said it must have been a week away. During the week she had not approached me about anybody visiting me. Question is should my friend pay up (she has no bumps on her car but some old scratchs)report the event to the police,notify her insurance company or just tell the neighbour that she accepts no responsibilty. thanks a lot for any response.
