I've been hurt too many times doing the 'right thing' and have been manipulated a few times in life... so I would never want to lead anyone on. I know how much it hurts to be on the receiving end... I just couldn't bring myself to do it.
If I tell someone something it will be the truth (or what I believe to be the truth) and if I'm wrong and proven wrong, then I will admit it --- may not be happy about it --- but I will admit it.
Not all women lead other people on... though there is this prevailing myth that women should or need to. I've noticed most younger women will feel they should manipulate and most older women tend to not see any point in manipulation. These are just observations... the conclusion I draw is that manipulative tendencies might be a sign of immaturity in a woman.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
