A fork is like when you and your friend are playing with toy cars and you decide to take a different path. Imagine you have a little car track, and you want to go left while your friend wants to go right. So, you both take your cars and drive on separate tracks. That’s a bit like a fork, where one thing becomes two separate things.
Another way to think about a fork is like when you have a book and you and your friend both want to write your own endings to the story. You start with the same beginning, but then you each write a different ending. So now, there are two different stories from the same start.
A fork can also be like when you have a piece of clay and you decide to make two different shapes out of it. You start with one big piece, but then you split it into two parts and make them into different things. It’s all about starting from one and making it into two different paths or things.
