My husband keeps coming out with statements that are totally unrelated to anything else we've been talking about or doing (for all I know, I do this too, but I don't notice it because it's following some train of thought in my mind); for instance, the other day we were driving down the road, miles from home, when he said "the drain in the back is really flowing right now." After processing that for a few seconds I finally came up with "the drain pipe out in back of our house?" Yep. Oh... good to know...
