Does she like me?????????

Ok so i was workin out at skool for b-ball and ima sophmore so i went to get a drink and this very hot senior who ive never met was starin at me and i didnt say anything to her and she asked me wat my name was first so i told her and went back to workout and i saw her starin at me thru a window while i was lifting weights so later she walked over to me at my b-ball game and jus said hi then walked away then she continued to stare at me so im thinkin she likes me and i cant stop thinkin about her even tho i dont even kno her name. Is this normal or weird?????
