It's no secret. The Partner and I don't always get along. There are times when we contemplate, longingly, life apart. But then I get back to the day-to-day realities of the outside world and I realize that I don't always get along with much of anybody, at which point it's him I drag my lonely ass home to for comfort. That must be, I have to think, why we belong together. It doesn't seem readily apparent when we're screaming at each other about the laundry or other things left undone, but this is the truth that continues to guide us:
We can tolerate nobody else the way we tolerate each other; we tolerate each other the way nobody else can.
