I am just mystified as to WHY. There is nothing wrong with that and for those that don't understand "commitment", I am really sorry.
Well, I assume the ultimate answer is...because someone in her family (whether that's the girl, her mom, her great aunt, her great great great grandfather or anyone else who has the power in her family to schedule her party) wanted to. Period.
And commitment towards a sport is good...but she also does have a commitment towards family, and let's face it, she was probably planning on HS graduation LONG before she hit HS and joined the golf team.
So you see her commitment to golf as being more important about everything else, while obviously she, or her family, feel the other way.
It seems to me that her future college soccer coach might like to know what this girl's likely commitment to the team is going to be - which is nil.
Hmm. Seems to me she's got at least two sports happening...seems soccer is more important to her since she's continuing it. So I can't see how her level of commitment to one sport means that the other sport automatically gets the same level...seems the opposite to me.
I personally rowed in Regionals instead of walking through my graduation ceremony. I felt that the graduation ceremony was silly (disliked my HS ceremony and this was just being held in the Fieldhouse of our gym, no biggie IMO) and rowing was much better. We got 4th out of 4 boats, so we weren't the brightest stars, LOL, but it was better than not rowing! And the other women in my boat were Juniors, so it would have impacted them quite a bit.
But I know there were other Seniors that walked instead of going to Regionals (two states away, by the way), and it wasn't a horrible problem.
Now I know you're not talking about graduation itself, but a party, but the graduation stuff CAN be so all-encompassing depending on family dynamics...unless you're there in her house, you just don't know anything other than...to someone in that house, this was more important than HS golf, and that's the end of the story.
