Yes they love each other. Yes we are lucky they are so close, so calm together. But they can get loud. Louder as they get older, even. I used to tell myself it was all going to get better, you know, as they matured.
It's like a form of denial - parenting - it's the only way to get through each stage, by the time you realise you are denying it, a new stage is about to begin.
But yes sometimes, I think it would be easier to negotiate with a terrorist, or nail jello to a tree. But all in all, they are great kids, and we are a happy family (shock therapy or not). You have to take the blessings as they come!
