Only three? Hell's bells, THAT is a pet peeve, lol! How the hell am I gonna restrict myself to just three? OK... I will include everything others have already mentioned, because, other than IT Guy's last one (which doesn't apply to me), I agree with them all. What can I say? I'm prickly! And I will never get tired of sharing my kvetching either! Bring on the complaint lists! LOL! (OK, I admit, js250's #2, is not a real peeve of mine, I just roll my eyes.)
This is gonna require some more thought if I am to narrow my selections! I have to say though that IT Guy's number 1, is one of my BIGGEST ever! But as I said, I have to spend time on this and I am incapable right now due to pain and medication, so I am going to post again later when I can think straight. I have a temporary list for now that may change upon further reflection (or not, who knows?)
1. Cruelty - this covers a LOT of stuff! To people, animals, etc. Mean spiritedness included.
2. Stubborn, willful ignorance - another one that covers a ton of stuff
3. True arrogance - you know, for example, the person who thinks they know better than you and therefore can take away your choices? (That's just one example.)
