So my friend ignores me for 4 days... (read description)?

And now she suddenly has good news and is my friend again and rubs it in my face. What is that? Loll Its like, until she had something to rub in, she wouldn't speak to me. She ignored me and now all of a sudden its back to the way it was before. I'm not gonna get all excited for her. Idk, what do you think?
