Hi. The phrasing in the name might be strange, but let me explain.
Let's say there is a coworker that you know nothing about and you only exchange with occasional "hi" nods. I find her really attractive, but unfortunately, at work, there is little to no chance to have a talk since we are on different floors.

It seems to me that just approaching her out of the blue is creepy as hell. Sending her a friend request is also a "no go", in my opinion. I might be wrong, of course.

What are some "natural" ways to approach? I must confess, I am definitely not a brave man in that I have never even tried to approach a girl I don't know. It has always been someone I met due to a common context.

In this case, however, I guess even being in the same building 8 hours per day doesn't help at all.

I'd appreciate any suggestions:)
