Yup, there are things you can casually say and made light of but revealing something personal about someone that's none of anyone's business isn't one of them. It's even worse when it's like an off handed comment like he's talking about something so irrelevant when in fact it's a secret that should be that person to tell (but the saying that, there's no such thing as a secret rings true).
When we watched Andrew's lakorn with Matt, I always thought there were tendencies that he was...the way he moved his hands and even the way he walks. But it doesn't change the fact, it's his secret to keep though. And to have someone tells the world...just isn't right.
