Does this girl at work like me or hate me?

Mildly flirt with her...don't come too strong...a girl seriously doesn't like it when guys er her up...at least the ones i know...put on a cool/in control front as you talk to her and see how she acts. Do NOT ask her out right away. If she doesn't like you now, from the sounds of it, you could possibly ger her too, but sometimes asking a girl right away will scare her. Just be a bit of a flirt.
