I talk out loud to myself a lot, probably more than most people do. Mostly this consists of sighs, grunts, exclamations! and other non-verbal noises. But it often consists of words, sentences, lectures, and even conversations. The lectures and conversations are usually about spirituality or my own stupidity or my perception of human stupidity. When i become conscious of the fact that i am making noises i can usually quit. I probably do this because i am autistic and because i have a preference for my own company.
