To make someone feel included you need to let them be a part of your group. You play fun games and not be mean to them at recess and after school.Then offer them a snack or a piece of candy or something like that. when someone says I don’t feel included you should say of course you are and wrap a hand around them so they know there included and your being friendly and including them. And you should always include someone even if you don’t even like them. If someone is bullying you it maybe means they don’t have any friends and are mad about or they might be jealous of something you have and they don’t so you should just be friends with people you don’t like or are mean to you and it might change both of your lives and make the person not feel so lonely.
