They give and take from each other: Sam teaches Freddie to stand up against others, have more courage, enjoy/ relax on life. Freddie on the other hand teaches Sam other necessities including manners, helps keep her grades up, and to take life a little more seriously.

There's obviously way more than that, but that's just the basics :)
