I often wonder what different people are thinking when I pay attention to them. Are you interested in such things?
After all, it can be not just one thought, but many rapidly flowing from one to the other, or even complete chaos.
Sometimes I'll be asked what you're thinking about, and I'll say, "I saw an inscription carved on a tree, and now I'm thinking about who this man is, what he felt when he carved the inscription.
Our thoughts are like a labyrinth, always wanting to find some logical conclusion!
