Express mail

Express mail is when you want to send something really important to someone far away really fast. It's like a superhero who can run really fast and get to where they need to go in no time.

So, you go to a special place called the post office and tell them you want express mail. They will ask you some questions and give you a special envelope or box to put your important thing in.

Then, they weigh it and ask you where you want it to go. You tell them, and they tell you how much it will cost to send it really fast. It might cost more than regular mail, but it will get there a lot quicker.

You pay the money, and the people at the post office put special stickers on your envelope or box that say "Express Mail" and the place it's going to.

Then they put it on a special truck or airplane that can go really fast and get to the other place really quickly. The people at the other place will see the stickers and know it's really important and needs to be delivered quickly.

Finally, the person who is getting the important thing will get it really fast, and they will be happy because they got it so quickly. That's what express mail is!
