Nothing keeps a relationship on its toes so much as lively debate. Fortunate, then, that my girlfriend and I agree on absolutely nothing. At all.
Combine utter, polar disagreement on everything, ever, with the fact that I am a text-book Only Child, and she is a violent psychopath, and we're warming up. Then factor in my being English while she is German, which not only makes each one of us personally and absolutely responsible for the history, and the social and cultural mores of our respective countries, but also opens up a whole field of sub-arguments grounded in grammatical and semantic disputes and, well, just try saying anything and walking away.
Just reading through 1/10th of the items on this list has made my head hurt. Some people just live in blissful acrimony I guess. Frankly, I would have buried her in the backyard by now but I have a pretty low frustration tolerance. Still, some people are masochists and like this sort of thing. Maybe it's the make-up sex.
