ELI5: Explain Like I'm 5

p.s.

"P.S." stands for "Postscript." It's a way of adding extra information or thoughts to a letter or message after you've already finished writing it.

Think of it like this - you're drawing a picture for your teacher and you've finished it. But then you realize you forgot to write something important. Instead of starting a whole new picture, you just draw a small note at the bottom called a Postscript that tells your teacher what you forgot to mention earlier.

In a letter or email, maybe you forgot to say something important and you don't want to re-write the whole message. So you can just add a P.S. at the end of it to say what you forgot earlier. It's like a little reminder or footnote to your main message.
