New Girl

I work in an office of about 200 people spread out on 3 floors. Most are married and the single ones are normally in their 20s.
Well, there is a new woman who started a couple of weeks ago, single and right in my demographic wheelhouse. I have been having some pretty lewd thoughts about her lately. I always make an excuse to go by her office.
I know all about the fact that you should not date someone from your office. But I really want to ask her out and find out more about her!
