Oh no, I wasn’t,’ said Lois by reflex action, and wished all the other things to which she was always replying, ‘Oh, no I didn’t’ or ‘Oh, no I’m not’ were half as true”

(Bowen 65)

This stuck out to me because it seems like Lois is always having to prove her innocence.  There’s no other way such responses could be a reflex action.  But at the same time, it doesn’t make sense because Laurence is the Oxford-oddball.  It could also be Lois trying to fit in, covering up for the things she might do that aren’t conventional – i.e., stay inside and cook and clean, etc.
