I feel bad replying to this, because these 17-year-olds are under enough scrutiny without the yahoos on this board salivating over whatever interpersonal drama they're dealing with.
However, I do want to say that this Wesfly story doesn't make sense. Whatever prior hard feelings the Wesfly guy glosses over here before the "prank" is probably the actual issue at hand. It's likely that the "prank" was just the most recent annoyance, but that whatever caused the initial rift between AS and L&L was the more serious/hurtful offense. Also, two high schoolers can't kick another kid off the team! That's the coach's right to do or not do, and would likely have to be tied to some breach in a student-athlete code of conduct that the kids sign at the start of the season. Anyone who has actually coached a school team would realize that the idea of two seniors being able to just decide to "vote" another senior off a team over a "prank" without coach/school administrator input isn't a full or accurate story.
In any case, I hope these three are getting some good mental, physical, and emotional rest after this cross country season. Hopefully they're getting guidance from more mature and caring people than those in the Instagram comments from this weekend.
