She prefers more mature clientele. I was probably pretty lucky myself to meet her being in my early 30's, but we hit it off and I've enjoyed every second we've spent together. Definitely not someone to book with if you're mainly just interested in hooking up because she's not about that at all. If she still sounds like someone you'd want to spend your time with, then it'd probably take a well written e-mail explaining what it is you're looking for in a date with her. Someone who takes the time out of their day to communicate properly definitely seems to score big points with the women who take their screening seriously.
Good luck, she's worth it!
