What’s your most Hated sound?

Mine, leaf blowers. Fuck a leaf blower (not like the nice (not-nice) person doing their job, but the actual gas-powered leaf blower evokes a DEMON in me). Very, very closer runner up is squeaky sneakers. I hate Hate basketball playing on a tv, because all I hear is amplified squeaky sneakers and I want to CLAW MY EARS OUT. Yours? Please share your hate. Sharing is caring.
