A wonderful, hot lady taught me a few things (THOSE things will be in the review! Different subject here) about the verification process that I thought might help other newbies.
When you ask a previous encounter to vouch for you with your next lady, if it's been any period of time since you saw her, give her a way to remember you. Your name is not on that list! "I was the guy who brought you the Star Gazers." In my case, that is how she will remember me, The Flower Guy.
Help that previous lady jog her memory about her time with you (other than what a stud you were) so that, when your next lady needs to verify you, she mentions that. "I saw her right after she returned from London and we talked about some of the same pubs." Get it?
