For a few years, Lily'd had a very good friend, Laura Edel. She had never really realized how much Laura was using her, and didn't really care about her.

-Lily?Liiiiiiiilyyyyyyyyy ? Hello ?

-Yes ? What is it ?

-I really need help with this... Can you show me the movement for this spell ?

-Um, sure. Here, you move your hand just like this to the right, and then back to shoulder-level, sharply.

-Oooooh okay right I get it.

-No problem. I... I thought it was in our D.A. lessons though...

-Oh. Maybe. It's just so much simpler when you explain.

-Uh, thanks.

-Um, Laura ? Can you help me study for the transfiguration test ?

-Sure thing, Lily. Helping you is the only thing I ever want to do with my life. All I ever do here is help you. All the time. Never have I asked you a thing in my life, but you do all the time ! I have enough, okay ? So let me be !

Lily was a quick learner. She'd experienced a false friend in her life already, and knew just what to do.

-Oh yeah ? So maybe you'd like to tell me exactly when you will take the time to give back all of the rubber bands that I've lent you when you lost yours, all of the pens I gave you when you forgot your pencil-case here, all of the books, the papers, the notes, the school forms and the documents that the teachers hand out in class that you lost instantly and that I duplicated myself because « your varnish was drying » or « you're so tired from working in class » when you were actually just watching Sirius Black !

Laura had the decency to blush, but Lily wasn't finished.

-I never ask you to help me, because I know you don't pay attention, usually you're the one who asks for the spells or the movements ! I am sick and tired of you !

They were in the common room, and everyone heard Lily's angry outburst. Laura became so very impopular that by the end of term she had applied for Beauxbatons and was never heard from at Hogwarts again.
