Funny topic this.... Just yesterday, while taking my son to play golf (still a beginner so a little bit of slow play... yet to be fair, we never got a full hole behind the foursome in front of us) we were hit into twice....
The first time we ignored it with a glance back... no animosity, no rancor, no hostility... everyone is allowed one really good shot that goes further than they thought it would.
No problem.
The second time they hit into us, I placed their ball on a tee in the fairway and took a practice swing in their direction in their full view with my driver....
There's wasn't a third time.
(of course, had they hit the boy, I would have needed a new driver... and he would have had to have his mother come get him while we talked to the police and waited for the ambulance.)
