Just Keeps Crunching

I love the way our brains just keep working on things even when we're not actively trying to do so. It happened to me again tonight. David said something and I responded with a tangent and then went off to brush my teeth. I didn't think I was thinking about anything, when all of a sudden it came to me what David had really been referring to. I think that's so neat. My brain just kept crunching through the data until it made the appropriate link, and then it presented me with the answer, pushing it to the front of my consciousness.
