My life is a WTF moment

People don't make sense to me. The older I get, the less sense they make. Given the option between something sensible and something idiotic, most people seem to take the idiotic option. I've lost track of the number of people I know who get into the most ridiculous relationships--you know the kind: you can see it falling apart from a mile away; they're in it for all the wrong reasons and they spend as much time (or more) complaining about each other as getting along, but they still think getting married/having kids/entangling themselves in huge financial obligations is just the bestest idea ever! And then once they've trapped themselves, they spend inordinate amounts of time crying on your ever-patient shoulder, whining about the other person and all the problems they're having. Well, not all of them whine. Some do their best to completely subsume their individuality in order to "make it work." You don't hear from them (they know you remember they used to have a mind of their own and a personality, and they don't like seeing the disgust in your eyes) until the whole mess has imploded, leaving them a broken shell only vaguely resembling the person they used to be. Then they start whining. And then you just want to beat them with a nail-studded club.
