Both of the ones I saw recently told me that I was not a usual sort of client and that I did things differently from their other clients. First, I think the first one exaggerated if not dead flat lied about that sort of thing. I did not take that to mean they were learning from me in any way. I think they are mostly insincere about such things. I am not all that interesting or unusual and I don't think most clients are. I also think they say they learn from clients as a technique - not a truth.
