"We rented a 4x4 while in Ireland last week and there was one incident where there was a little old man driving a little old car v e r y v e r y s l o w l y and DH was talking about driving over him - DS (6) thought he was serious and was v. disappointed when he wouldn't actually do it.
Twas funny at the time! "
