The most recent thing I've realized that I dislike is excessive indecision. It seems to be symptomatic of our generation's general lack of a clear destination. Yes, everybody occasionally needs, and deserves, some time to collect their thoughts and get their shit together. Maybe a few days. But when you find yourself needing four weeks to "think about" the future of a relationship that has lasted barely that long, it's time to pack up and move on. "I don't know" more often than not means "no." If you wanted it, you'd know it; if you don't, stop wasting my time.
Moral of the story: there comes a time in every relationship when you have to either man up and play ball or get off the field.
