'I walk straight into them': 17 women on the petty hill they will die on.

I like to think I'm a pretty laid-back person (my family is scoffing as they read this).

For the most part, though, it takes a lot to grind my gears, get under my skin, boil my blood… whatever idiom you want.

But, sometimes, things happen that make my (self-appointed) laid-back mask slip right off.

In these moments, my petty alter-ego makes its cameo, preparing to strike.

Watch: Does your relationship have these 'microcompatibilities'? Post continues after video.

The thing is, this mask really only slips at the smallest of inconveniences. And I mean small.

You could quite literally call me ugly to my face and I would probably get over it in two business days. Maybe you had an off day? Maybe my makeup had an off day? C'est la vie!

But if you don't give me a courtesy wave when I let you merge in front of my car?? Consider yourself an enemy for life.

Of course, I know I'm not the only one with a petty alter-ego. But, I was curious about everyone else's barometer for pettiness.

So, I put the question to you guys: what is the petty hill you will always die on?

Needless to say, you didn't disappoint.

17 women on the petty hill they will die on.

"I always make a point of walking straight into someone if they don't make room for me when getting off a train or elevator before trying to get on," one woman told Mamamia.

"If a car starts to tailgate me when I'm going the speed limit, or even a bit over, I will purposefully slow down," added another.

"I will always correct someone who says 'me and' in instances where it should be 'and I.' I'm a grammar girl, and it drives me up a wall."

"When I worked in retail, I would always greet customers by saying, 'how are you?'. If they didn't answer and launched right into ordering, I would wait until they were done, then repeat, 'how are you?' until they acknowledged me as a person."

"On a plane, I will push my way before you if my aisle is exiting," a fifth woman said. "Just because you got up before the seat-belt sign and pushed your way into the aisle doesn't mean I'm letting you through! And yes, I know we are all waiting at the baggage carousel together."

Another said they would always "insist on manners" like "asking someone to repeat their question or request until they say 'please'."

For a seventh respondent, the card game "UNO" hits a nerve. If they catch someone pronouncing it wrong, they will step in.

"It's 'oo-no', not 'you-no'," they insisted. "Uno is the Italian word for 'one' — like the one card you have at the end when you say 'oo-no!!'"

For another, "telling people to pick up their rubbish/cigarette butts/dog poo if they leave it on the ground", is a must.

On public transport, "when someone puts their bag on the seat next to them, meaning others can't sit down, I will make them take it off so I can sit there, even if there are other empty seats".

"Niche, but telling the men at the gym who use the assisted pull-up machine for regular push-ups to get off the machine — beyond selfish, drives me insane."

Another admitted they will, "stare at people who are talking/being loud on the quiet carriage until they shut up".

One will say, 'the line starts back there', when people cut in.

For another woman, a new act of pettiness came out when she fell pregnant.

"At the moment, lots of randos are touching my pregnant belly, so I just say, 'the baby is facing the other way, you are actually just touching me', and they get awkward and stop".

"Not yielding my elbow spot on the armrests when I am in the middle of the row on the plane," said someone else. "I deliberately try to keep my elbows at the back of the armrest to give people the front. Yet they still want it all. I am in the MIDDLE people!! Give me this."

When responding to road rage, another woman chooses to kill 'em with kindness by, "blowing them a kiss".

"If a group of two or three people walking toward me refuses to move into a single file on a narrow footpath, I will shoulder charge into them," a further added.

And, finally: "If I do a small courtesy for someone — hold a door, let them go past, pick something they dropped off the floor — and they don't say 'thank you' or acknowledge the act, I will always say, loud enough for them to hear, 'you're welcome!' I can't stand rude, entitled people, and I will definitely die on this hill."
