I see you completely professional and smiling as you confidently walk up to old T and shake her hand...'it is great to see you again, I look forward to your presentation.'

I totally get the 'yikes' factor but I also think that it is likely going to be harder on old T than it will be on you. First, this is your domain that she is coming into. It is with people you are comfortable with and an area you are the expert in. I wouldn't say that you are 'above' T, but you are definitely equal with her in this setting.

I ran into T outside of the office two weeks running. We were in the darn elevator heading up to the office, and he was talking to someone else. At first I was the one who was uncomfortable, but I busied myself with my phone and acted like a stranger. Later in talking with T about it, T emphasized that it was UP TO ME, whether we talked outside of the office or not. I also realized that it was likely uncomfortable for him as well, since he was trying to respect my privacy and figure out how to respond.

It is up to you how you encounter your old T. She is bound by confidentiality, and will have to follow your lead. That puts you in a very empowered position...so don't forget that!

How do you see yourself encountering old T?
