This is what annoying
, overdressed, loud people say in restaurants when they hear someone else mention a book, movie or play but cannot remember it's name.
Guess what, no one tells them, and they do not

Paradoxically, these are the SAME people who take delight in giving away the end of movies, books and plays that you have not seen.
In a word, evil.
