My Mean Friend

Hi everyone, long time no see. One of my friends, gabi, has been acting so mean to me and every one else lately. The other day, her friend lauren go hit by a soccer ball. We took her to the nurses office. We all told each other to cross our fingers. But then i said out loud, " Cross your fingers to lauren." Gabi said, "you dont have to tell the whole stuped world!!!" Then not only that, she elbowed me and my friend, jenny! What should i do? please comment any advise!!! Thanks! bye!
