I think this girl likes me..........?

i caught her watching me play volleyball, when she realized i noticed she left right away, earlier the day she smiled at me walkin by my clroom, looking at me, or is it possible she was smiling earlier, on msn, i told her i was drinking and she said drinks your place then ? she said when are you going to bed, i told her 6am, she said sweet maybe me and * girls name * will come by, and i told her her and her friend could come , then she kept saying, were on our way k? were comin kai ? be right over kk ? like how many times does she have to tell me, she sent me a webcam invite .. for her and her friend, she said k your not gonna accept it ? so i did, it was mostly her on the camera though, could a girl be this excited about me sharing my beers ? lol
