Proust and Euphemisms

The blogger in the link below takes exception to one of Proust's "euphemisms," but I really liked it because Proust  didn't use whatever the  current euphemism was (and there were probably many).  Instead Proust used something very specific to Swann and Odette, something with meaning to them, and I thought that was an example of his greatness as a writer. 
Has anyone noticed, by the way, that "hiking the Appalachian Trail" has become a NEW euphemism, and that in our times, these new expressions come facing at us before the ink is dry. 


Here is the blog link:

A cattleya is an orchid, (shown above, and look at Google images if you want to see hundreds), and Odette always wore one on her decolletage. 


The other Odette, who doesn't wear flowers but likes to grow them.
