Well matters on how well you know them but as the saying goes, fortune favors the bold. If you don't really talk to them or show your worth, you'll probably never be noticed.

Yeah, I agree with dashkatae. It does take a little effort to get someone to notice you want to get to know them. You can always start off with some small talk just to try and set the grounds for all that. Find some common ground and base the conversation on that for starters.
