I am going to take a wild guess that YOU would not have failed your class, as JHD did, so this situation would have never materialized in your academic career. Parents are people and they can become embarassed by the irresponsible actions of their kids. The comments did seem a little bit of overkill, but to say the education and deportment of their son is not their business is not right. You are a dad, so you know, sometimes a child of 17 or 18 needs as much or more parenting than a three year old.After reading the article, and having 5 kids of my own, I understand the ambivalence the Days are feeling with JHD's performance. It's our job to teach them and instruct them. However, at this point, it's up to JHD. He's of a majority now and the contract for his scholarship is between GTAA and JHD. His parents have no say. They can support and guide, but the decisions, choices and consequences are on him.
If that were me and my parents came out publicly like that, I'd tell them politely that they had no right to discuss my private business in a public forum and to keep the comments to themselves. He may be acting like a kid and need the kick in the pants that he'll likely get from this, but suggesting his scholarship be pulled is crossing a line they have no business crossing.
