I understand the so called "right" thing to do Kevin..but as I said earlier so easy to be judgemental, due to my own indiscretions I tend to be more sympathetic and look at the bigger picture..dont throw stones in glass houses approach.
The number of people and so called "friends" I know who judged me for instance, that I know drink too much on the golf course then drive home, cheat on their wives etc...come on..it is game and the kid ended up doing the right thing.
I agree he did what he thought was the right thing to start with...and I have never understood the whole dq after the fact thing anyway, adjust the scorecard after the fact and move on...it appears this was an honest mistake.
Unfortuantely Kevin is right...those are the rules, which in essence left the player with two choices, keep quiet and deal with it, or becoma a dq victim.
A third option of telling the officials and getting the extra stroke..SHOULD have been an option...imho
