I remember walking back from Westerham in Kent to Sevenoaks, it was Sunday and a friend and I had forgotten there were no buses. (1970's) In a state of boredom we decided to count how many wolf whistles we got on the long walk back!!!!! Don't ask me how many there were, but we didn't do bad. We were 16/17 and can't remember when the last time was, but know it was LOOOOOOOOOOOOONG time ago!!
