I think the people who wonder if they know their T or adamant that they know them, are emotionally attached to their T.
After going to therapy off and on since I was 20, I only "cared" if I knew one and it was the one I was attached to.
I'd much prefer not caring if I know them. The other folks I know who go to therapy never "cared" about that either way and they don't understand why I became attached.
