Everyone has irritating habits; those strange little quirks that drive the people around us loco. But some people go above and beyond the label to become habitually irritating. That’s why the term “justifiable homicide” was created.

Here are the 7 Habits of Highly Irritating People. Taken individually, they’re tolerable; but collectively?!

No eye contact during a discussion. It’s hard enough making small talk at parties or business meetings. But if the person you’re speaking with is looking over your shoulder, down your shirt, at the ceiling–or anywhere but at you, just walk away. They won’t notice.

Intense eye contact during a discussion. Ever feel like you’re talking to a serial killer? Chances are, their eyes have been boring into your soul for an intense 10 minutes of conversation. They don’t glance away, they don’t break eye contact for one second–and they never blink (except that one time when the guy’s eyelids blinked sideways.)

Interrupting conversations. So you’re talking to a co-worker/friend/cousin/mortal enemy, and they suddenly decide your story is too boring–and they start telling you about their trip to the Bahamas. Move on.

Being judgmental bastards. All your co-worker/friend/cousin/mortal enemy can talk about is how everyone sucks. Because perfect.

Being easily offended. There’s always that person who can take anything you say and turn it into an insult. “My, that’s a lovely dress you’re wearing.” “What does that mean?! Why are you lookin’ at my dress?!?”

People who don’t listen. You can tell when people stop paying attention. They get a distant look in their eyes, and you can hear the squeaky hamster wheel in their brain slowly come to a stop. Just start rambling nonsense or making up new swear words. It won’t matter. They’ve checked out.

People who have to be right. You could be discussing gravity. Or the polio vaccine. Or the societal impact of The Simpsons. But it doesn’t matter what you’re talking about, because this person ALWAYS disagrees with you–and backs up their argument with baseless “facts.”

Another irritating habit? A person who points out irritating habits. Have a good Tuesday. If that’s even possible.
