She smiles after you open so you,

"Ohhh. . . look at those cute dimples . . ."

"blah blah . . ."

"Hey, but don't get a big head now. Dimples alone won't get you a date with me. . . Although . . . I am developing this urge to give your dimple a big fat kiss! . . "

"Oh no! or Oh my God! blah blah blah."

"Oh Jeez! Look! That girl just fell down!" (Point your finger. She looks away and you plant a kiss on her cheek)

She'll smile, smile, and smile but she'll go, "Oh, you tricked me!"

"No, no . . . you missed it. She really . . . Oh shit! She fell again!"

Now you don't even give her a chance to reply and you go something like, "So do you believe in the importance of the first kiss?"

On and on and on . . .

Millions of different ways to do this but the important thing is to keep pushing them to the next level. Have fun . . .
