(Don't get me started on the trend of alternating dramatically whispered conversation scenes with dramatically loud action scenes.)
I've been watching The Shield
on Netflix on my iPad at the gym, and I've found that while most of the actors are easy to hear, the actor who played their captain favoured soft-spoken, dramatic line readings. Therefore, every time he's in a scene, I have to crank the volume up - and then, when there's a shootout in the next scene, I'm nearly rendered deaf.
While I'm on the subject of annoying things, it drives me up the wall when someone who asked me to do some work for them comes up to my desk and stares at me expectantly - and is stunned if I have to say "I'm sorry, I haven't had a chance to do it yet." I don't know if this person thinks that I'm sitting around all day twiddling my thumbs, but he never seems to think that I might be busy with other work, too.
