So there's this hot girl I work with who has curly long brown hair and a pretty fair sized rack, but I've noticed interesting things about her behavior. When I ask her how its going, or just saying hi, she just ignores me but when I actually ask her a real question about work or her personal life she won't stop talking to me. She has an interesting life to be honest, but she hasn't made any sexual advances towards me. I'm unsure as to if I should persist chasing her in hopes that she'll be a worthwhile plate, or just give up because she only speaks when I ask her questions or bring up casual conversation. I'm not getting the message that she doesn't like me, because she never says "go away" or anything like that, she just flat out ignores me when I ask her how its going or just saying hi.
