Note I mean "small things" like it's ultimately something that doesn't really effect you in any major negative way, but it's still something that bugs the crap out of you anyway.
-People making "wet smacking" sounds with their lips and mouths
I really don't know why, but I can't stand this sound. I think it started because my dad always ate bananas with his mouth open for some reason (it's literally the only food he eats like that, I have no idea why), and the sound of him chewing up a banana with his mouth open drove me crazy. It's not just when people are eating either, some people just end up doing it while talking as a result of something else I'm not sure of. This is actually why I DON'T listen to ASMR videos where the video is a person talking, because almost every single one of these videos I always hear that "wet smack" sound and I can't stand to listen for any more than a few seconds (I stick to ASMR that's just ambient noise). For some reason this is always MORE noticeable when a person is whispering.
Why does something as small as a sound people make with their mouth, usually unintentionally, drive me up the wall? I have no idea, but for some reason any time that sound hits my ears I need to get away from it as I know it'll bug me to no end.
-Having to switch the HDMI cables on the back of the TV
One that's more a result of me wishing for a little extra convenience, and yeah this annoyance is a "first world problem" to the highest degree, but eh it still bugs me anyway. The TV I own only has one HDMI port so this means I keep having to switch the cords for cable, the Wii U, and Xbox 360 constantly. I think the reason why this bugs me so much is because I had to do this very thing with my old CRT TV as well, just with composite cables instead of HDMI (usually switching between the Wii and PS2), so I thought when I got a newer TV this wouldn't be an issue anymore. Nope, new TV, same old annoyance.
