I only seen her once and I dont like her

Theres an girl who I only just met last night but I really dislike her , shes fake and everything is off about her , I got bad vibes as soon as I seen her but I didnt say anything to her , I was sat down and there was loads of other seats and since she sat before she tried to make me move , all because she was sat there before , I didnt understand what she said at first so Isaid i dont mind but then her friend whos new ( first night ) came to appolgise because she was being rude. I didnt move. Anyway , I hope she doesnt come back or at least isnt an regular ,We never even spoke to each other before. She became instant best friends with the new girl who I got along well with , but I can really sense she really dislikes me too even though I havent even had chance to even learn her name.
