Maybe cut people some slack ... if they realize it a little later than you'd like, what does it matter? They've realized it. What? Can't you be a little patient with people? I think the saying should be, "Dump him if he doesn't love you perfectly immediately. And if he tries to get you back, don't take him back." And that, my friends, is quite possibly shortsighted.
Mack's version: I know strength, because I've been weak. I know courage, because I've been afraid. I know wisdom, because I've been a fool. I know love, because I have lost it. I know life, because I have experienced all of these things. My hope is that when I come to know death, I will be considered strong, fearless, wise, and loved by those who knew my life.
