Intelligence.
Perhaps you’re lacking so allow me to shine some light. Shape, size, race of the man? Familiarity, clothes he’s wearing, the way he walks, where you and he are both walking, what time. Is he following you, or not? These are just some simple starts to identifying people. This ought to help you tremendously. However, we must admit, that many women are simply brain-dead stupid, very low intelligence, and honestly cannot identify people or recognize danger. Gullibility, innocence, naivety, easily duped, the “victims” of most crimes.
To seduce, trap, or ambush an intelligent woman would probably not work, because she would see it coming, and sense the danger, correctly. Properly and immediately identifying threats.
I apologize for revealing you in this manner, that you don’t have the first clue. This response can be a helpful lesson for you. Are you 12 or 13 years old?
You are like Ecmandu, except the female form, with vague generalizations and universalities. He claims that all women are evil, and you, all men are evil.
Both of you…are wrong.
