Perhaps because The heart is a lonely hunter? Perhaps the victory of optimism over caution?I do not disagree with you at all. However, knowing how difficult it is to prove a charge or rape in a court of law why are so many women careless about meeting almost total strangers in circumstances and in locations where their security & safety is "iffy" at best? I don't get that at all.
Something drives people (not just women) to go beyond their comfort zone, in an effort to reach out & make contact with another person. & sometimes that drive simply overpowers the instinct for some caution.
