I really like the question and I hope a lot of people come on board to answer.

I talk about small things from my past that I have never talked about - maybe things from when I was a teenager, and conversations I have with members of my family that actually appear pretty simple, but I find painful. Recently I worried that my T felt I should be bringing other things, but these things were meaningful to me. I make a list beforehand otherwise I wouldn't think of these things.
