I hate this question too! It's normally asked as, 'so how has your week been', 'how have you been' etc and the last time she even said ' I know I always start by asking this...' and I said 'yes and I will always just answer it the same - yeah yeah, all good, fine etc'
I do understand why she asks but I find it very hard to get started in the therapy hour and direct questions like this actually do not help.
I hate it in the real world too and I tell people off for asking, but I can't do this to poor T because she is just doing her job and I think that it is the one time it is actually appropriate, whether I answer or not!
