By accident, I saw a profile mentioned this: "I want to find a NORMAL MAN!!! Is there any one left?" How do you feel if you are a gentleman and you are checking this profile?
Frankly, it's quite realistic that she just wants to date someone who is "Normal". But when she put this on her profile, things are changed? Just think some gentlemen may reply like this: I'm not that normal guy. I'm special, I'm unique, and I'm always standout... Don't you think such sentence will stop some great gentlemen from reading your profile further?
So when making a profile, we may also pay attention to the feelings of your readers (your potential match). If some of your words make them feel not good, you fail.
