Later on into the night, she also started asking about favorite comfort TV shows and when I mentioned I enjoyed Buffy The Vampire Slayer, she acted like she felt bad for me because I like that show. She also acted superior when my guy friend said he liked both Star Trek and Star Wars and said he couldn't like both. She also proceeded to install an application onto his Playstation without asking him (she doesn't live there and they've only been dating for about two weeks) and started playing her music without any consideration about anyone else's musical tastes (mine is completely different and is similar to my guy friend's).
She's a nice girl but those interactions were just odd and I'm just scratching my head over them.
