Nathan said he didn't have any fun at his new school this week . Do you know why ?   I think he hasn't made any new friends yet . He's just a little lonely .   He really misses his friends from our old neighborhood .   Without a doubt . Maybe if he knew he doesn't have to give up any of his old friends to make new ones , it will be easier for him .   How do you propose to help him understand that ?   Well , we can help him keep in touch with his old friends .
