"Hello Petra" said Sonea while she stared at the girl, trying to discover what person she was. "I'm a third year" said Sonea with a frown, why did she asked that? she looked old enough to be a third year right? Hmm... "Can i sit besides you?" asked Sonea while she pointed at a free space besides the younger girl. "Do you like it here? And, it may sound rude, but are you are pureblood?" She wanted to know it, being friends with a halfblood was possible, but a with somebody from a muggle family? Nooooo, that was not possible, so if Petra was a mudblood than she would not try to make friends with her...... Not even if she could use the girl for her own good, she was simply too good to be in the presence from somebody like that!
