As an experiment back in my teenage days, I tried to eliminate all ums, ehs, likes and pauses in my speech. More than anything, I loathed the vagueness and repetition of “I/he/she was like…”, or even just “like”. Hated the way my peers stumbled around every sentence as though they were only partially convinced they should be speaking at all.
