@Germlat,
We need, Germie, before we run away with ourselves, to decide whether what the lady deemed to be faults were actually faults. If they are not, as is often the case, then the chap is not lying and not mocking her affection and thus there is no deceit. Thus her anger is misplaced and signifies her as being a bad-tempered little ratbag always wanting all her own way.
I am incapable of even thinking of such an expression never mind writing it down. I presumed before I checked that Fulton was an American.
