I browsed through and I couldn't find something like this... Forgive me if I have been my blonde self and just gone past it. It's been known to happen u.u

So! Pet Peeves! xD
I'ma paste the Wiki definition:
A pet peeve (or pet hate) is a minor annoyance that an individual identifies as particularly annoying to them, to a greater degree than others may find it. Examples may be; poor table manners, sloppy kitchen hygiene, smoking, grammatical errors in written passages, inconsiderate driving or lazy co-workers.

We all have them... and sometime throughout the day something bugs us. Like an example for me. Last night I was trying to get some sleep. And at 1am the start construction over the road. My room was shaking. The inconsiderate behaviour of workers at 1am bugs me xD Of course they were doing their work - I shouldn't grumble.
Another pet peeve of mine is people chewing in my ear. @_@ Drives me INSANE! GRRR ;;
