The importance of note - taking

A client of mine recently asked to see the notes that I had been keeping of our therapy sessions, and because the Freedom of information act does guarantee the client's rights to access these notes, I (somewhat reluctantly) handed them over. The client had the following questuions re the notes.

a) Who is Lola and why did I need to call her?
b) What did 3 apples, butter, sugar and self raising flour have to do with her relationship problems?
c) Vet. Was I thinking of consulting a vet re her case?
d) Why did I scrawl "Change oil and water". Was this some kind of abstruse therapeutic metaphor?
e)Cortisone cream. She couldn't recall ever having uttered those words in a session.
f) Why had I written my signature 30 times on one page, alongside little drawings of planes and cars and stickmen?

I explained that I like to free associate when listening to clients, and that those items were indeed a record of
the precious ($200 a session) work we had been doing together.
