When it comes to dating or making friends, many of us have a list of potential red flags.
From pet hates to serious concerns, these can be anything that makes you immediately cautious about someone you have just met. As such, they are often highly individual.
Despite this, a woman has ignited an explosive debate after sharing one of her red flags.
And lots of people were keen to give their opinion on her controversial viewpoint.
But for reasons soon to be explained, she claimed people always make her "wary" when they are "over-familiar types within minutes of meeting them".

Explaining her aversion to such people in a post to Mumsnet, the woman wrote: "The other day I met a couple that my partner knows. They seemed friendly, particularly the girl.
"She talked a lot, I mean really a lot, which is fine, maybe a bit different from me but that's who she is. But she was starting to get quite deep and emotional and I had only just met her.
"Telling me about dark periods in her life and how X point was the only time she'd felt she had any self-esteem in life, this kind of thing. At this point, I'd met her for 15 minutes.
She continued: "Maybe she wears her heart on her sleeve or is just very open but it just really seemed too much for someone I'd known for 10 minutes."
And it sounds as if she has had a negative experience with a similarly-minded person before.
"Another person I met a couple of years ago was like that. Within an hour of knowing her I knew her relationship history, the relationships she had with her family, that her ex had been controlling, and so on," she added.
Her post concluded: "I later tried to make friends with her but she just didn't reply to my messages and then randomly cut my partner (who she'd been mates with for years) out of her life, refusing to meet with him and deleting us both of all social media for no apparent reason. I guess she had had own issues.
"I think since her I'm always a bit wary of these super over-friendly and over-familiar types within minutes of meeting them. Am I wrong to be? Anyone else?"
And it turned out she is not the only one, with several people agreeing with her points.
"No, I think you're right to be wary of oversharers," wrote one person. "They love to be the victim and love the drama and attention of it all."
Another said: "I also don’t like oversharers or overfamiliar people, seems to demonstrate an early lack of boundaries."
But some people suggested the woman was being unreasonable.
"People are just different. I don't think it's necessarily a red flag. And neither is hugging someone you've just met 'fake', suggested one comment.
A second added: "Yes, I think you're unreasonable. You had a bad experience with one person who overshared with you and now you're wary of all people you meet like that. Why?
"Imagine if I told you I'd had a bad experience with a Welsh person so now I'm wary of all Welsh people. What would you think of me?"
