I see this one is surfacing again in the search queries. About once every three months this seems to happen. As a public service, we must once again address the single dumbest fucking question a woman can every ask:
"How Can I Be Aloof Around a Guy?"
Were you able to follow along there? Being aloof around a guy is a dumb fucking idea. And you are a dumb fucking person if you try it.
I get that girls aren't wild about openly approaching guys. I appreciate that is a basic fact of nature. But, at least conform to the basic rules of how girls approach guys.
Being aloof -- ignoring a guy in order to attract him -- is a dumb idea. If he's attractive and he knows it, he is looking at other options besides you! If he's attractive and he doesn't know it, he's gonna need a little help from you realizing you're serious about your interest in him. And if he's unattractive -- well, you're gonna have to build him a paint-by-numbers kit to explain to him that you like him.
Female aloofness is a no-win plan. Don't do it. Ever.
