Brains

I'm playing my harp at a home for mentally challenged people today. Since I'm taking the kids with me, I had a conversation with them about what to expect and what not to do (i.e., don't point and stare or make comments or ask loud questions). After I tried to explain how the people's brains don't work quite the same as ours, Noah said, "Are they very contagious?" I'm glad he asked that, because I wouldn't have thought to explain that we don't need to be afraid of catching anything. Later, Noah asked me how TVs work, so I was explaining about how our brains assemble pixels into images, and Noah asked, "So...the people you're playing the harp for, can they watch TV, or do their brains not understand pixels?"
