I don't think this is strange either. And I am glad that you did ask for it.

My T once had said just the right and perfect words to me when I needed them. But soon afterwards I had forgotten most of it. Especially the precise wording he used was simply so beautiful. I wished for a long time after I could have had that in writing or on a tape to listen to it...
So I do think this is quite normal to feel that way!
