very excellent question!

do they want to hear that we are doing well ?

do they want to hear that what they are helping us with is actually helping?

do they want to hear that I don't need them anymore?

do they want to hear that they are the best damn therapist I have ever had?

do they want to hear that I have listened to their problems that I hope they will be ok?

do they want to hear that it seems they have more problems than I do and I won't bring mine up any more?

...ooops earthmamma...seems I might have some issues with therapy.
