Upu
Okay kiddo, so UPU stands for Universal Postal Union. Do you know what the mailman does? He delivers letters and packages from one person to another. But sometimes the mail needs to go to different countries! That's where the UPU comes in.
The UPU is like a big club for mailmen and post offices all around the world. They work together to make sure that mail can travel from one country to another safely and quickly. They have rules and agreements about how much it will cost to send a letter or package, how long it will take to get there, and how to make sure it doesn't get lost.
So when we send a letter or package to a different country, the mailman in our country follows the rules of the UPU to make sure it gets to the right place. The UPU helps make sure that we can stay connected with our friends and family who live far away!
