Exit with a flair

When its time to leave dont get too verbose. Dont say stuff like "fine, i will call you then, take care now, goodbye", thats not a good exit at all for a guy because its common and it will not generate any attraction in her. Just say something blunt and casual like you really dont care about leaving her company, something like "see you around" (in a bland tone without excitement) is perfect. Remember that less is more. If she says something like, "call me sometime" or "lets hope we bump into each other again" it's great, just give her a smile and move on. Dont ever say something like "Oh I would also love to bump into you again" or "it was great talking to you, we should do it again sometime", thats a huge turn off. Keep her guessing about if you really liked spending time with her. Be subtle guys, thats the secret of seduction.
