I have a girl at work that always looks at me from afar but quickly looks away when I catch her. When we close she doesn't make eye contact and when I say hi she act really really serious like she hates me. But she always kind of comes infront lf me almost dances infront of me I dont know how to put it she kind of puts her hands between her legs kind of sticking her butt out? bend over a little? does stuff like laying on counter and collegues telling her "whats the matter with you"
