The guy who moved back in with mommy and daddy. Maybe he's changing careers, maybe he lost his job and has to get back on his parents' payroll, maybe he just realized being an adult male is too hard. Whatever the reason, unless he just graduated from college last week, this guy's evolutionary trajectory is moving in reverse. A man who wants to crawl back into the womb won't make a good mate, or even a good date. We've already suffered through dating men with curfews … in high school.
