i am also a teen, but i do have my pet peeves on the course.
1) the people who just constantly use mulligans. like on every other shot..
2) slow play. dear lord, this is so aggrivating. to me it really screws up my play. cuz what happens is that your sitting there at your ball, for like 5 mins, and all your doing is just thinking about the shot. taking practice swings, and thinking about thr shot some more. to much thinking isnt good!
3) Idiot Adults(no offense). if any teens are on this forum, maybe you know what i mean. ok so lets say me and my pal are playing one day and this really slow foursome is in front of us. all thru the first three holes we hint to them that theyre really slow, and that we are getting frusterated, but they wont let you pass. they like ignore you, all most like they just dont flat out respect you cuz your ''younger then them'' and a ''child''. But then whats really fun is when we do catch up with them big time and they HAVE to let us pass, we hit our drives and they stand in awe. cuz most of the guys out there we can beat.
so yeah... thats my $0.02
