This works best when you have isolated your target.
It's a really simple concept, but it takes a little practice to work well.
When you're having a good conversation, you can actually force a physical IOI by slightly
lowering the volume of your voice, bit-by-bit, while speaking to your target. If done correctly,
you can tell she's super interested because she'll slowly start to lean in, closer and closer to hear you.
Great to test the waters before a kiss close.
If you dont do this properly however, you'll hear her say: "What?" and you might lose her interest in that
particular story or whatever you're blabbing about.
Try it for yourselves and see! My non-PUA buddy showed me this one, and it's pretty slick haha!
