Two boys were at the forest.

One, pale skined, brown haired, his name was Remus Lupin. He was a half-blood wizard.
The other one was long, golden haired, pale skined too. His name was Legolas, and he was an elf.

Two boys were chasing butterflies, jumping on the trees, gazing through the little river...
''Legolas, we need to talk.'', Remus suddenly said.
Legolas strange looked at him, he didn't know what was the problem.
''What is it?'',he finally asked.
''You know that I'm going to Hogwarts in a month, don't you?'', Lupin asked him nervously.
''Yes.'', he quietly answered.
''And you know I'm gonna meet new people there?''
''Yes.''
''And... Well, I'm gonna have new friends there. But I will be here every summer. And you are like a brother to me.''
''What are you trying to say?'', Legolas asked, but he knew what Lupin meant.
''I will maybe have new friends there, but I will never forget my brother.''
''Thanks Lupin... Hey, maybe we could give each other a nicknames and when someone mention that word, we will remember each other!'', Legolas had an idea.
''OK! You will be... Hmm... I know! You'll be Greenleaf!'', Remus shouted.
''Cool! I like it. You can beeeee... Moony!'', Legolas replied shouting.
Both of them laughed.
They knew, even they will separated for a long time, they would stay brothers.
