Have a look at The World's Best Friend you created together.
Inside the outline are all the things that make them a good friend. Those words describe the kind of person they choose to be - kind, funny, caring and helpful.
But people can't see what's inside our hearts. What they can see are the things we say and the things we do. That's how friendship grows. That's why you wrote those around the outside of your picture. Every kind word, every helping hand and every smile is a way of showing other people the kind of friend you are.
The best thing is... every single one of us gets to choose those actions every day.
