| "You are my best friend." It’s the nicest thing you can 1 to someone. It’s also the nicest thing you  can 2 someone. Good friendships begin in middle school. It’s the 3 you begin to develop your own personality. Your parents aren’t around so you 4 lots of time every day sharing your life with your classmates. You talk with them, you work with them and you become friends with them. But 5 them will become your “best” friend. Best friends are the people who like you and 6 you the most. They are the 7 who are easy to work with and easy to have fun with. Sometimes it’s 8 to find a best friend. And sometimes you can 9 a little lonely. But just because you don’t have best friend now, it doesn’t mean you 10 one in the future. Best friends seem to find each other as if by magic. And when you find your best friend, the magic will last forever. | |||
