Okay kiddo, let's talk about exaction.
Exaction is basically like when someone takes something from you without your permission or doesn't give you something they promised you.
Let's say you have some yummy cookies that you want to save for your special snack time, but your friend comes over and takes one without asking. That's an exaction! They took something that was yours without your permission.
Or maybe your parents promised to take you to the toy store, but then they didn't have time to do it. That's another example of exaction. They didn't give you something they promised you.
Exaction can happen in lots of different situations, and it's not nice when it happens. It's important to treat other people's things and promises with respect, just like you would want them to do for you.
