Pointed set

Okay kiddo, imagine you have a big box of toys. Each toy has a pointy arrow pointing to it and that arrow means that the toy is part of a special group called a pointed set. The pointed set is like a club, but instead of people, it has toys with arrows pointing to them.

Now, let's say you have another box of toys that also has arrows pointing to some of the toys, but there's no special club or group for them. That box of toys is just a regular set without any points.

So basically, a pointed set is just like a regular set, but it has a special toy club with pointy arrows to show which toys are in the club. Got it?
