Michel de Montaigne

“ I love
to follow them, but not to be so servilely tied to their observation that
my whole life should be enslaved to ceremonies, of which there are some
so troublesome that, provided a man omits them out of discretion, and not
for want of breeding, it will be every whit as handsome. I have seen
some people rude, by being overcivil and troublesome in their courtesy.
Still, these excesses excepted, the knowledge of courtesy and good
manners is a very necessary study. ”
