Today, you need to pay attention to the one person who is doing their darndest to avoid you! Emails go unanswered, phone calls are never returned. They either did something they don't want to tell you about, or are afraid you already know about it! Reach out to them and be proactive about the situation. They aren't going to fess up until it's far too late to fix whatever they've broken. So it's in your own best interests to track them down and make them spill.
