I hate fake voices
I really hate it when people put on different voices of any kind. I can't stand it.
When people do an elaborate "haaaaaaay" instead of a normal hey, it goes through me like nails on a board. My sister has picked up a slight southern accent somehow and I can't stand it. Like, that's not your voice stop it immediately. Adult baby talk makes me want to puke with rage. In movies if you can tell somebody is putting on a fake accent I have to turn it off. It doesn't seem to bother anybody else this much.
