I'm sure your T knows about "confabulation". Maybe that is what occurred here? Confabulation is when your memory and your imagination get mixed up as to what REALLY happened. It's not like an intentional lie at all. It's just that sometimes our imagination fills in when our memory fails, and it FEELS real to us.
Anyhow - it usually takes a LOT to annoy a good therapist! I know this from experience. I'm VERY annoying and my T still liked me.
