So if you want them to be honest with you, you better be honest with them. If the personal ad is selling a truck and you want a motorcycle, don't waste your time or theirs responding to the ad. There are too many ads in too many places for you to compromise your self respect or waste your time responding to ads that don't have what you want. In deciding what you want, be as specific as possible. Or you'll wander through the personals settling for less than what you'd be compatible with.
Life is too short to settle for second best.
I'm not looking for you to support me or solve my problems. I am looking for a relationship that can turn into something that will make us both happy. I am an open book for the right person and a closed book to game players. If you're looking for a relationship based on honesty, trust and communication, let's get together for a cup of coffee and talk. Hopefully we can start out as acquaintances, become friends and the romance will follow.
