Susan Walsh's essay on the female rationale of shit tests completely awakened me to the hidden motives of female interaction. PUA's can defend from shit tests, but they don't understand them. Betas think they understand them, but they fail. To be an Alpha - fuck the lingo right now- to be a Man, you need to not only be able to recognize, but to understand them as well. Only then can you understand your woman and be the man she is looking for.
