I for one could not give a hoot if you jump off the dock, pilon or roof -- jump & miss your a mess (it won't be me or any of my family).
I also understand traditions (remembering back to college "Frat" days) -- doesn't make them sane or right!!
However last week-end I personally watched an adult (term used loosely) trying to encourage what appeared to be their 5-6 year old daughter "to jump"!! The little girl wanted no part of it but the father kept insisting as (what must have been her older brother's & sisters/ friends) were jumping off beside her. I couldn't bear to watch so we continued through the NWZ and left!
Okay, now you can skewer the newbie
