attraction, so here's some tips to help you out:
1. Disqualification doesn't require you to be mean or rude. A great disqualifier can even be a compliment. What matters is the fact that our brains are hardwired to believe the greatest rewards are those we have to earn and work hard for. Try the line: "You'd be perfect for my friend." It's a quick phrase to throw out that breaks her presumptions and causes her to wonder why she isn't perfect for YOU.
2. If a set doesn't seem to hook with your opener, don't try to forcefully disqualify by calling attention to the fact that they're seemingly uninterested. This is defensive action on your part that only makes things worse. Wait until you have a real connection before you disqualify. You can't break rapport if there's none to begin with. A little emotional push away is a lot more effective when she's already moving towards you.
3. Try slipping some simple disqualifiers into your conversation. "We can't be friends anymore" is a funny thing to say if she doesn't share your love for "The Goonies" or for your favorite cartoon growing up. Keep in mind, a good disqualifier is only a temporary barrier. It's designed to be overcome. You're not trying to ensure you truly can never be together.
4. Disqualify based on your own taste. Within minutes of getting to know a girl I'll say something like, "I could never be serious about someone who doesn't read as much as I do." or "I can't fully connect with someone that isn't interested in energy work like massage or yoga." If she's into you, you'll be surprised at how quickly she'll begin to qualify herself.
