I observe them from afar. I listen to their words and get a feel for who they are. I don't make a move until they've said or done something I can discuss intelligently and enthusiastically. I like to keep myself in short supply. I'll suddenly reveal myself and be really bright, then pull back just as quickly, back to nonchalantly observing from afar. I keep people in the dark about what I feel, enjoying the process of watching them wonder and discover, maybe even subtly toying with them and giving mixed signals - a quick glance when it seems like I'm ignoring the person, an extra moment of eye contact when hanging out with a group of friends, an almost undetectable little smile, a mysterious sigh, asking a simple favor that looks like it could lead somewhere but pulling back casually when it's done. My style is to basically pretend that I don't even notice the person but drop a few tiny hints and see where things lead. I tend not to worry too much about any 1 particular person; this is just the way I constantly operate. If I go out in public and talk with a lot of different people, whether they're new or old, I'll be doing this sort of stuff automatically and just observing the results, seeing how people react and taking what presents itself, if I choose.
