What does it mean when a girl sits and turns her body towards you?

...is it becus they're attracted to you? there was this girl who sat in the front row and on break she went outside and notice me sittin in the back. then wen she came bac she changed seat and sat on the same row as me. and she kinda sat wit her body towards me....i thought this was wierd cus wen she was sittin in the front she sat normally, facing forward...this was the first time we ever saw each other.
