Every now and again you might get a text or call from a random number, with some poor sod at the other end assuming they're chatting away to 'Jill' or 'David'.
But usually that can be settled with a simple 'Sorry love, think you've got the wrong person!', before everyone has a good giggle and goes on with their day.
But one person didn't have the awkward-but-polite exchange we're all used to from random contacts - quite the opposite.
Screenshots from a conversation between two unknown people were shared on Twitter by someone who wrote: "Sometimes I think I should delete Facebook but then I come across content like this. Please read this."
The screenshots show how one person was messaged by a mystery woman on Instagram, who launched into an interrogation regarding her boyfriend. A poorly-spelt interrogation, we might add, but to keep things authentic to her sentiment we won't try correcting anything - so good luck.
"He likes all ur pics? Why would he do that if u didn't speak to him?" ol' mystery woman asked the person.
"He's my boyfriend can u not get ur own."
The other person replied to say she didn't know who her boyfriend was, explaining she had no control over who liked her pictures on social media. A fair point, to be honest.
But that didn't seem to appease the other woman, who continued: "Wearing makeup and skirts for everyone's and skirts for everyone's boyfriends to see. Why would I ask my boyfriend for? When it's ur fault for doing it on insta not bein funny but if I seen someone wiv a skirt I would luck so obvs he is."
The accused calmly replied to say she didn't know who the woman's boyfriend was, and said she was clearly 'very insecure'.
But the woman hit back saying: "My boyfriend calls me insecure so clearly you've got that from him ur fucking rude u stupid c***. I'll fuck you up u think I'm messin mate??? Do you coz I swear if he likes anova fucking picture off ur stupid fucking profile I'll go fucking ham.
"Didn't want an argument my boyfriends cheated on me in the past an fort u was the side thing."
Then the other person fired back with some sage advice, telling the jealous girlfriend not to stoop to her boyfriend's level, saying: "If you don't trust him then end it."
It seemed as though the wise words had worked on the woman, who, in a weird twist, went on to say:
"I know what you mean now my minds at ease. Thank you.
"But do you think I should break up with him?"
Saying what we are now all thinking, the other person said that they personally would - to which the woman replied: "Fucking new u wanted him you whore reverse sicology getting in my head ur not havin him."

The screenshots have gone viral on Twitter, where everyone's saying the same thing.
One person tweeted: "The most shocking thing in all of this is the grammar #sicology."
Others said they'd come across similar people, with one writing: "The funny thing is some girls actually think like this and there's no way you can ever convince them."
A second said: "Omgg like...I deadass have spoken to a girl like this and all I could do was feel bad for her like...poor insecure girl, we all insecure but that's like extreme w a side of ppl feeling super bad for u... "
Blimey. What a bloody rollercoaster, eh?
