What does this mean

Imagine there is this person that you've practically seen sitting right across the hall for months, but never really have taken notice of. When you unexpectedly get to work on a project together, you actually talk to this person the first time. You hit it off right away and you're surprised he turns out pretty different from what you thought he would be. You probably never even thought about it that much, what kind of person he was. He was just someone who was there, you know, some guy across the hall. You've barely had the time to figure it out, now the project is done, you may or may not get the chance to see him again. It really depends on if you want to. I know exactly why you're hesitating. You're thinking, what if he didn't feel like you hit it off at all. What if he never really been aware of your existence either, and still isn't.

Check out Wong Fu's "This is how we never met", very inspiring.
