Or is it possible that since she is going to school on a soccer scholarship that she has camps, orientation or anything else that may interfere with the final tournament? If she does, then she is doing the right thing pulling out of the preliminary one too in order to give the JV player a shot at both.
Or, maybe she has summer employment for those college expenses, didn't anticipate at the beginning of the season that she might not be able to get the time off.
There are so many valid reasons she could have withdrawn from the competition that to just jump to accusing her of being a loser is pretty drastic.
And let's face it, if she is mentally done with golf and did just decide to have her party, the team should be saying good riddance. She certainly wouldn't play her best if she didn't want to be there.
So, give the JV kid a chance. Really, the team still has its top 5 players to get those 4 scores. And the JV kid might just surprise everybody.
OP, did your daughter get one of those
AAA awards? Because I am sensing a bit of jealousy of this girl and her family.
