I'd say try to talk longer. All the more feminine qualities of the world are your (and mine :) keys. Say hello to everybody, even if you don't have a reason to. Ask people about themselves.. Nothing who doesn't like talking about him or herself. And HUMOR. Remember that the only thing you two would have in common right after you meet someone is humor. Make fun of anything but THEM AND THEIRS. Throw lotza that STUFF in and you're ready 2 go! Good luck.
Be nice; Share, offer some of your lunch if they have none. Ask them about themselves, people like to talk about themselves. Talk with confidence; meaning, loud (not yelling), few stutters, and keep your head high. Don't use sarcasm, no dry humor. Be funny, but don't overuse jokes. Smile. Smell good.
