Tactical Dating Maneuvers

I recently learned that a friend of mine is a "pre-emptive breaker upper." As soon as she feels a hint that she's going to be thrown overboard, she quickly pushes the other person out of the relationship raft and into the shockingly cold waters. My only thought on this is what if there were no weapons of mass destruction? What if the reason for odd behavior was not a breakup, but actually a proposal in the works? This brings about the thought of little red flags that lead to a relationship civil war. For example, once, while I was dating a girl, I realized that I had never found out what she likes to do when we weren't together. Nothing was her answer. Nothing! How could that be? I questioned her about hobbies, sports, and media. She did nothing. She liked nothing, and so therefore all she did was nothing. Another friend told me that he dated a girl with no sense of humor. I said, "Don’t you mean a poor sense of humor?" He said, "NO sense of humor." I would rather date a girl with no sense of smell than one with no sense of humor. In fact this would be ideal. After all, I have a friend named Curtis who once said, "Dating is nothing more than holding in your gas all evening, while trying to think of intelligent things to say, and spending money on other people's wives." He's such an Optimist!
