Classic Poem

I know a friend, very strong and good. He is the best friend in the world.
I know another friend, subtle and sensitive. He is certainly the best friend on earth.
I know another friend: very quiet and shrewd, there is no friend so good as he.
I know another friend, who is enigmatical and reluctant, he is the best of all.
I know yet another: who is polished and eager, he is far better than the rest.
I know another, who is young and very quick, he is the most beloved of all friends.
I know a lot more and they are all like that.
