Then #close when yoo feel like you have had a solid interaction. The longer the interaction, the more chance the number won't flake. If you can, instant date. Girls never flake after an instant date
Finally - text her within 10 minutes of leaving her. You want to keep the interaction going continiously, otherwise when you call or text in a few days, the memory of the fun you had together might have faded and you might just be 'some guy' again.
