No one knows how to behave anymore, so Mamamia's Modern Etiquette Guide is here to help.

Can you demand guests take their shoes off at your house? 

Is it rude to talk on the phone at the register, or just part of modern life? 

And do you have to invite every kid in your child's class to their birthday party? 

There's one thing that's become pretty obvious in 2024: no one really how to behave anymore… or exactly what the rules are for being a decent human being in society.

And it's not our fault. We were all basically locked inside for two years and forgot how to function. (What a wild time).

But don't fret, come and nestle in our bosom as we introduce you to Mamamia's Modern Australian Etiquette Guide. It'll be your new best friend — or your worst nightmare if you're doing a lot of these things wrong.

Watch: is it ever okay to regift stuff you got for free? Post continues below.

Each week, we'll be guiding you through the do's and big-ol'-don'ts when it comes to group chats, play dates, dinner parties, gift giving, travelling, behaving on public transport and in the workplace.

But first up it's weddings, and boy are they a hotbed for bad behaviour (you're thinking about that one groomsmen who did that one (bad) thing and that one wedding, aren't you!?)

Each week, we'll be adding more etiquette guides, but until then you can feast your eyes on these:
