The posts lately about work and SO vents got me wondering what everyone's pet peeves are in general.
I have several, because I am that person.
The one that stands out in my mind the most is basically any mouth noises (smacking, chewing, swallowing, crunching, dog licking itself etc.) I am really sensitive to sounds though, so basically any repetitive noise is almost guaranteed to make my eyes bug out of my head.
Another is when people spell my name wrong, specifically when replying to emails where they have it right in front of them. I don't have a weird name. My name really only has 2 variations in spelling. Why is it so hard for people to spell it right????
Flightiness/ acting like an airhead. I have a few people in my family who act this way and think it's cute and funny. It isn't.
Not clearing the time microwave if you stop it before it is finished. Whyyyyyyyy????
Your turn. Go.
ETA: Improper grammar. i.e. improper uses of the words your and you're; to, too and two; there, their and they're, etc.

Re: What are your pet peeves?
To mouth noises - YES. Especially chewing/chomping food with their mouth open.
Flicking/pinching - I HATE IT. HATE IT. HATE IT.
Not changing the toilet paper roll when it's empty. ESPECIALLY when they leave the new roll on top of the empty one, or on the bathroom counter. WHYYYY?

Misuse of the word "unique". It doesn't mean unusual. It means that there is only one. Your baby is unique. Your wedding dress is not, unless you made it yourself, or had it custom made.
Grammar: "Me and my fiance...." Is your fiance mean?
Yeah Tiny Houses are this new trend in housing and HGTV has been all over it. They're typically just a hundred square feet or so and the bedroom or extra space is usually a loft above the rest of the house so it's just like sleeping on a loft bed in college again. 2 nights ago I watched an episode where a couple bought one for 60k and change and then their rent was 540/month for the land in this tiny home park!
When posters don't come back to either thank you for advice or follow up on the situation. It just leaves a bad taste in my mouth after knotties spend time giving you advice.
Know-it-alls. I am sorry, but you can't know everything. I have a friend that when she does this, I have to resist hard not to roll my eyes.
Incorrectly using the word "myself". "Fi and myself are planning our wedding." No, it is FI and I are planning our wedding.
Chewing with your mouth open or talking with your mouth full
OMG - when DH leaves the last little bit of strawberry freezer jam in the jar and doesn't get a new one out of the freezer. That last bit is the consistency of ice cream syrup and that is not what I want on my infrequent PBJ. Get a new jar out!!!
Incorrectly using accept and except.
The jerk who KNOWS his/her lunch blew up in the community microwave and doesn't clean it up.
I stand on escalators because I have been having knee problems but I stand to the right. That allows for people to walk up them on the left. If you looked at me, you wouldn't know that it's painful for me to walk up them but after years of playing soccer, I no longer have any cartilage in my knees.
I can't tell you how many times I have walked onto the redline and people use a seat for their bags. Drives me crazy. Especially rush hour. I also hate when it's a packed train and people do NOT move into the center. It creates a bottle neck and less people get on and it takes longer. Move to the center of the car.
ETA: yes!
Ha! I am N Quincy to DTX. The same people make me stabby too.
That one is coming from the mouth of experience a' la yesterday.
