This is more of a perpetual annoyance thing than a grumpy old man thing, but....
I can't stand the sound of my voice, the accent in particular. It sounds fine to me via the bone conduction we hear ourselves with, but gratingly irritating via the usual compression waves through which we perceive sound. (If you've ever wondered why you sound different to yourself compared to when you hear yourself played back on a recording, while everybody else says it sounds just like you, that's why.)
I have some kind of disastrous, unholy mesh of hillbilly, hick, southern, he-must-be-partially-deaf-and-probably-learning-disabled accent that just makes me sad. I'd forgive anyone meeting me for the first time for assuming I'm mentally retarded. I manage to forget about it, mostly, and it's never really hurt my self-confidence, but when I'm forced to hear myself, I have a lot of sympathy for friends, family, and coworkers who are afflicted constantly with the sound of my voice.
I'm doing some software tutorial videos for faculty and staff use, and it requires me to listen to myself while checking and editing them. It's hard to believe we don't have standards that prohibit this kind of thing. What kind of workplace that takes itself seriously disseminates videos that make people say "Oh god, here goes that gator-humping, inbred sympathy hire again?"
I just wanna get done with these and then go another several years without having to hear me again.
