Crazy money.
Weddings cost money, both for the couple throwing the big day and for those attending.
However one bride-to-be has planned a celebration to lavish that her guests are expected to pay £10,000 per person in order to be part of the ceremony and reception - because the wedding is happening in the Caribbean.
In a post on Mumsnet, the unnamed sister of the bride shared the story and explained how she just couldn't justify spending that much money to attend a wedding.
In a post she wrote: "My sister and I have never been close and now we live far from each other so contact is basically limited to a WhatsApp message on special occasions.
"She has invited us (me, partner and baby) to her wedding in the Caribbean next year at a cost of around £10,000 per person which is money we don't have.
"My sister got upset when I told her we wouldn't be able to attend and my parents offered to pay for us to go to appease her, but I declined the offer as I don't feel comfortable taking that much money."
"Is is unreasonable of me to turn down the invitation?"
The woman continued: "Even If I would take that much money from my parents, I would rather put it towards a house than a two-week holiday.
"I feel that if it's that important to my sister that everyone can attend her wedding then she should have picked somewhere more affordable or she should be offering to cover part of the costs for guests.
"My sister earns minimum wage, but her future husband is a high earner so she lives a life of luxury without having to work for it and I feel like because of this her view of money is distorted and she thinks everyone can afford the lifestyle she has."
She adds: "Is is unreasonable of me to turn down the invitation and my parents' offer to pay for us to go?"
Commenters were definitely on her side.
Perhaps unsurprisingly, people were definitely on the side of the sister.
Commenting on the post, one Mumsnet user said: "Hahahahaha! She wants you to spent in excess of £20,000 to go to her wedding when you don't see her from one year to the next? No. Not happening. You are not being unreasonable!"
Another commented: "Your parents are prepared to fork out £30k for you to attend your sister's wedding? I would definitely be having a different conversation with them. Decline the invitation, it's not a summons."
A third replied: "Sorry I fainted at £10,000, then fainted again at £10,000 per person. You are not being unreasonable, much better ways to spend a small fortune. Her fiancé and your parents must be loaded."
