It really depends guys, there's really no clear answer. A HB8 I'm talking to now gave me the shit test because she's been hurt a lot in the past, and is trying to avoid "players". With those types of girls, they want to see if you're really interested or just playing games. If she flakes and you brush her, she'll think "he didn't really want me anyway." The same thing happened to me years ago with a mature HB7 that was afraid to date me because of my age, AND we worked together. What it took was me telling her in a nutshell that she can put me through all the "tests" that she wants, but I'm going to plow through them because I want her. Girls like determination, they feel prized. A few days later, I TOLD her, let's grab a bite to eat this evening, I'll call you when I get off work. She said okay immediately. You can persue a girl without coming off as an AFC. Just let her know that you see right through her. I've brushed plenty of HBs and lost them trying to play it too cool. But now I'm starting a "No HBs left behind" campaign.
It takes a bit of feeling her out, and you have to recognize that. Canned approaches can only take you so far.
