There are quality, date-able, interesting and attractive people for all of us out there. Be honest with the other person and yourself. We are an educated bunch and have something to share.
Honesty works, at least as far as reducing the chances of getting a vicious rejection.
I'm certainly no hottie, but I get a better response when I'm honest than otherwise. And ladies, don't be disappointed when a guy acts like himself. Just do the same for him. Communication is key, because you never know if the person standing next to you trying to think of how to introduce himself might be the next love of your life. Or at least worth a free drink or two.
