Yes, I tell her "Oh, that's good!" when she connects something I haven't and I agree with her analysis. I tell her when something she says or a way she says it makes me feel good, that I appreciate her saying it or saying it the way she did.

I often say "I like when you..." or "I appreciate when you..."

... call me back
... don't get irritated with my phone calls like I'm afraid you wil
... reassure me
... say that so gently because it's easier to take in that way
... share a laugh with me
... help me stay focused when I need to and let me wander otherwise

... tell me I'm your favorite client and you wish all the others would just go away.

.. Okay, I made the last one up. But she could! And if she did, I would give her postive feedback!
