Batten down the hatches...there's a storm a brewin'. There's no telling when it will end or what kind of destruction it will cause, so better safe than sorry.
That's the way I feel sometimes about life with Bear: it is as unpredictable as the weather. One minute it's all sunshine and love, and the next it's raining cars on my head -- literally. But once the deluge is over and the remaining showers have passed, it's sunshine and love again.
That gets exhausting, let me tell you. Imagine staring at the sky constantly, always wondering when the next storm will hit? That little cloud over there? It looks all cute and puffy and white, but don't kid yourself. It can turn into nasty weather faster than you can say "What the hell did I do to set you off this time???"
