Those who can't do
.......teach. Those who can't teach, just stand up front and talk bullsh#t to graduate students while demanding that they be taken seriously. Speaking personally I stay well clear of anything with the word "collective" in the name as its bound to be full of know nothing tossers of the sort described above.
Hope your tongue has healed :^) Good luck.
PS I never heard of Henri Cater Persol but he sure makes good sun glasses. I own a pair. Sunglasses, cameras - they both have lenses so you can excuse his mistake surely??????
