I know I would have offered to replace, but that's just me...I'm working on appreciating how unique people are and accepting that my right isn't necessarily "the" right.
I also know that when i got involved when my kids were teens and they were upset over some friendship drama, or something a teacher did or said, it always came back to bite me. They were mortified. It took me awhile to learn that lesson and I sure learned it the hardway.
