I can stand someone saying “uhhm” once or twice or even three times but if they won’t stop I’ll immediately write them off. It’s the “mmm” sound that tears it. I myself say “uhhhh” or “aahhh” but never, ever fucking “uhhm.” It’s not a huge biggie to most people, I realize, but to me “uhhm”-ers are right up there with people who throw their heads back and howl obnoxiously as they sit with four or five friends in cafes.
The film is Generation Um… (5.28, Phase 4). All actors who were really good looking in their 20s automatically become interesting as hell when they hit their 40s and grow short scraggly beards.
