The 27 green flags that tell you, almost immediately, that someone's a good person.

We talk about red flags a lot, particularly when it comes to relationships.

If the majority of your friends don’t like someone.

If a person refers to an ex partner as “crazy”.

If they attempt to fast track the relationship, in a way that could be deemed clingy or possessive.

Red flags are really important because they highlight subtle and sometimes imperceptible behaviours that someone likely isn’t good for you.

But we don’t spend an awful lot of time acknowledging the green flags – the tiny things we notice in other people that indicate they’re probably a bloody good person worth getting to know.

We discussed green flags on Mamamia Out Loud. Post continues below.

We spoke to a bunch of women about the green flags to look out for when it comes to new people. Here’s what they came up with.

They speak to waitstaff politely, or anyone in the service industry

They love animals and are kind to them

They speak about their parents with respect

They actually… text you back

They ask questions about you

They remember details about you from previous conversations

When you walk away from them, you feel good about yourself

Your friends and family love them

They ask how you are, and genuinely listen to the answer

They’re passionate about something, and they pursue it

They revise how they think about things based on new evidence and information, and are curious to have their opinions challenged

They compliment other people behind their backs

They listen to the person everyone else is talking over

They ask questions, and are open enough to say when they don’t understand something

They’re not constantly checking their phone

They include people in group settings

They respect your alone time

They say thank you

They ask if you’ve eaten

They put their rubbish in the bin and clean up after themselves

They get excited about the stuff you’re excited about

They return what they borrow

You’re actually yourself around them

Your pet likes them. A lot

You can disagree respectfully

When they say they’re going to do something, they do it

When they say the four magic words “leave it to me”

Of course, something like your pet warming to a new person isn’t enough evidence to confirm that someone is unequivocally ‘good’. It’s just a green flag, which might indicate they’re gentle or kind.

You know what else makes you a good person? Donating blood! Post continues below.

When you notice multiple green flags in someone – perhaps the most important being how you feel when you walk away from them – then you might have just met someone, either as a friend or a partner, who’s very, very special.
