I am 24, single, engineer living and working in the PNW. I have been working at a company for almost two years now, and I have obtained this great cubicle spot right by the window, looking at the main front door of the building our company is located in. A new company moved into the building, and this one really attractive female caught my attention. We made eye contact, and started waving to each other through the glass as she walked in and out, happening several times a day. I finally worked up the courage to go say hi to her, introduce myself, and gave her my business card. It doesn't have my cell number on it though, just work contact information. its been a couple days, seen her a couple more times, but no word from her.

my question is, should i leave it alone? what should i do?
