It has been a great pleasure *focussing* on Col. Brandon, which has left me quite cross eyed with his charms 8)
The Cambridge International dictionary of English defines 'charm' as;
"a quality which makes you like or feel attracted to someone or something"
A *quality* I think is the important word here. Now Willoughby is said to be charming, but 'that' is really *not* his quality. What he has is, again according to the same dictionary, and as I see it, is;
charm offensive, which is an intentional attempt to achieve something by using charm.
My conclusion is that while Col. Brandon is charm itself, Willoughby uses it *intentionally* as something that is not a part of him - like a weapon.
So after settling this I proceeded further, and found out that as a reader I am absolutely charmed by Brandon's total personality, which is a *quality* he never loses.
Willoughby according to the above definition sometimes forgets to turn the 'charm offence' and we see clearly what he is, especially when talking rudely about the Colonel. He does this early on in the book, and for me he never fitted the definition of a charming man.
We have been discussing all his qualities these past weeks, so I won't repeat them, but one could really write a long list of all the *qualities* of the Colonel which *make him attractive* - thus qualifying him as one who fits the definition of 'charming'.
