What does it mean if a girl teases, makes fun of you, jokingly calls you things like 'idiot and creepy' talks silly with you, laughs with you, calls you sometimes by your full first name when your known by your shortened name. Also saying things to be playfully mean, yet we can have serious conversations about work and other stuff. She also says aww sometimes when I do something, not to her but in front of her. Is she just attention seeking? she's 23 and acts daft like this when I'm with her. She also has a bf.
