Yes, T's are not listening for "facts" in all we say, but for how we are saying; my T once described it as "listening for and going with the emotions". They're kind of riding the waves :-)

But they get to know us, just like a friend would or like we would get to know someone else; why would they forget what is "important"? It's a relationship, not just a "lecture" we're giving that they may/may not remember; if it is important to us, they'll know by how we present it and they'll work on it with us right then and there.
