I don't believe that ALV is old fashioned or shocked regarding sexual activity - as a domestic violence therapist, she would have heard many, many shocking things. I believe she is using that as an excuse to testify she mis-spoke, or didn't ask questions she ought to have.
And again, when an evaluator takes notes, they might miss something, they don't add - they omit. ALV added 'gas cans to go to Mesa', and 'walked in on child computer *advertiser censored*", she didn't forget to note something, she added detail. That makes no sense.
