Of course she should pay whatever it takes to repair it -- or if it can't be repaired then whatever it takes to buy a new one -- and then plus tax. You shouldn't be the one inconvenienced for her mistake; she should be the one inconvenienced for her mistake. The only exception to this would be if her family is very poor and cannot afford it without significant consequences, in which case you should probably let it slide, since it was an accident. But really, if a family has a house, either bought or rented, then they can probably return ~$200. It may be the case that the girl doesn't have $200 for herself, and she has a hard-ass family that makes her work for it, and then the situation gets a little gray. But if the girl has $200 in her own stash of money then she should pay for it. And yeah, I'm assuming it's ~$200, though it wouldn't make a difference if it were $300.
By the way, your grammar is HORRENDOUS. How the hell did you come up with a title like "someone craked my Ipod Screen"? It seems to me that you would have to put in a lot of effort to make a title that grammatically obscene. It's not just rules of grammar, it's haphazard things like why you chose to make "Screen" capitalized and not "someone" (the first word in the title). Also, why is it "Ipod"? Haven't you seen at least a thousand iPod ads? It's "iPod". Now if it were in all lowercase letters, or even all uppercase letters, then it would be less miserable, but this kind of wayward writing I just don't get. I seriously had to read your story (which in itself is had to read) before I understood what you meant by the title. And the title is supposed to be a clear introductory statement that sheds light on the article.
