Truth is - this comes down to character. We live in a world that has marginalized character. We list all the reasons that it's ok to break our word and all the anecdotes that "support" our reasons for breaking our word - but it comes down to the willingness to break our word. It always boils down to plain old fashioned selfishness (when there is a lack of cause - like a coaching change or academic shortcomings)
Some people (most actually) are comfortable with breaking their word and being that person. They still think they are a person of character (because cognitive dissonance is a powerful thing) while behaving in a way that is completely in opposition to that reality. You are the sum of your actions. I am sure this cut and dry approach makes most people feel uncomfortable and that's fine.
Most people are average or below average in every way. Character is just one of those ways.
Make a promise - keep a promise. End of story.
If you don't then you need to accept the fact that you are a person who's word is not worth anything and shouldn't be surprised or disappointed when people return the favor.
The staff at VT doesn't deserve this. They are people of character and they keep their word. It's unfortunate that not everyone adheres to that same moral compass.
I could totally agree with this if the party being referred to wasn't 15 when they agreed to the deal. There is a reason kids don't have the legal ability to make a contract. it is unfortunate and Tech isn't any more to blame then any other school - one thing for sure is the kids are not to blame...it is the system that is broken.
The "system" is only one part of the equation...the parent is where the buck stops.
