Does she fancy me or hate me?

there is a girl that i really like and i think she really likes me also, but a few days ago i accidentaly double footed her in the shin while playing tennis, she seemed to find it quite funny at the time but the next day she came in and she had only one leg, she seemed quite ticked off about the whole thing, which I dont really understand, she hasnt said a word since i did it, except for "WHY DONT YOU GO AND WATCH BUTCH AND SUNDANCE: THE EARLY YEARS?" What do you guys think?
