So theres this girl I know from work. She actually works at another branch but I see her fairly often.. and we talk on the phone a lot when theres nothing to do. This is what Ive noticed:

-When I see her, sometimes she'll put her hand on my arm or shoulder when shes talking with me.. and she does seem excited or at least interested to talk to me.
-She's asked, "Sooo do you have a girlfriend?"..also tried to figure out how old I am, where I live and stuff.. always has questions like that.
-She talks about doing hypothetical things with me in the future.. "o.m.g I would love to just quit work and go backpacking across Europe.. wouldnt you? We should just do it." etc.

Ive never been good at reading signs.. since its a coworker I kinda have to be a little cautious about just asking her out. Is she just flirting or does it sound like shes interested?
