If you think writing about your dislikes is a turn-off, your wrong. In fact, it’s been my experience that daters who declare their standards right away are often more successful than their polite counterparts. It would seem that being totally up-front, right from the start, is the best way to gain an online strangers respect.
Don’t worry about sounding bitter. If you’ve got something to say, say it. Even if it’s not pretty. You might be surprised at how much your frank and honest words can put other daters at ease.
