What does it mean if a girl keeps imitating your actions (I am a dude)?

Hi, there is this my co-worker she usually imitates me in things I do. like I once told her i went to this restaurant the other day, on that weekend she went to the same restaurant with her friends. I told her that I went to this shop, boom suddenly she is doing the same.

since we work in the same company, usually she keep imitating or doing the same things I do. it doesn't bother me, but I am just curious cause I myself sometimes imitate people but when I find like a good habit or something, not everything they do, so I find what she is doing kind of.. weird that's all
