When umpiring I truly hate to hear the following cobinations!
1. Parent A " keep your elbow up.." or some directly opposite of Parent B's advise
2. Parent B "keep your elbow down."
3. Parents & an an occasional coach yelling "Good hit, after a player flies out! If you don't know that isn't a hit, why are you there?
4. The worst is Parents, some players and an occasion coach saying we score a POINT or we scored (x number of) of POINTS.
