There are particular young people that are always resistant to talking about anything more than small talk. I try not to push or pry when they make that known. It can be hard to watch them stuff all the hurt and pain away so I just continue to tell them that I am around for them if they change their minds.
To my surprise I had a call today from one of these friend who took me up on my offer. I was busy in a meeting and they left a message. By the time I got back to them they were past the point of wanting to talk. I laughed and realized that I had missed my window of opportunity. They laughed in return and said: "I have to keep it interesting."
