I would first, just be myself. After years of changing myself to be what THEY were, or what I thought they wanted me to be, I learned the hard way to just be ME. They always tell us that and yet for some of us it seems so hard to learn. Tell them whatever fits the topic of discussion and what you feel comfortable telling about yourself. There are no shoulders or shouldn'ts in this case.

You have to accept you as you are before they can. Big hugs.
