Most people get a cake and a couple of presents from their parents on their birthday.
But when Japanese student Yuma Hasegawa turned 20 recently, his mum and dad handed him a letter stating that they were resigning from their parenting duties.
And it's brilliant.
Here’s the full letter, as translated into English by Rocket News24.
Happy 20th Birthday!
Notice of Expiration of Child-Rearing Services:
As of October 4 2015, your father, Yoshikazu Hasegawa, and mother, Chiaki Hasegawa, have completed their duties of raising their child: you, Yuma Hasegawa.
Going forward, please become a proper and responsible member of society, like your father and mother.
In addition, should you continue living in the Hasegawa family home, please make a monthly payment of 20,000 yen [£108] for rent, utility, and grocery expenses.
Also, please be aware that should you ask for a loan from your parents, interest will be charged.
Points to note upon reaching the age of 20:
You must make compulsory national pension payments. If you put this off it will cause problems, so make the payments.
Should you commit a crime, your face and name can now be shown on television and in newspapers. You will also have a permanent criminal record.
You can now buy alcohol and tobacco products. Do not drive while intoxicated.
You can get married without your parents’ permission. However, they may not emotionally accept your wife as their daughter-in-law if you don’t discuss the situation without them beforehand.
Think responsibly about the future and set aside an adequate amount of savings from the money you earn.
Please enjoy your life as an adult.
According to the Metro, Yuma Hasegawa has assured everyone his parents sent the letter in jest.
In fact, he's actually been paying rent money for the past year.
