My advice for IP is to focus on yourself. It's why you are there. I spent my time focusing on everyone else. I spent my time listening to everyone talk, helping them, making friends...basically fixing everyone else. Which was actually against the "House Rules" of the place I was at. I feel like I wasted those two weeks because I'm not in a safer mindset. I met some good people, sure, and it's only natural I should do what I did because it's what I do for a living, but it's not why I was there and now I may be looking at possibly going back only two months later.
Get to know him, there's nothing wrong with it. But like Nammu said, take it very slow. Focus mainly on your recovery and your needs.
