I wasn't going to write any more about the sociability/reticence topic of the past few posts, but one more, short anecdote has popped into my consciousness.
While this isn't something that I remember first hand, I have been told that I wasn't exactly a verbose child – surprise, surprise. I didn't talk particularly early or a lot, but I have also been told that I soon moved on to phrases. Apparently, my father would piggy-back me around the house. There was a scripture calendar on the wall, and Dad you point to Peter, James and John. One day I said, "Peter, James and Me" (yes now you know my other name). If I've got the story right, it's one of the early things that I said.
So, I guess that, even early on, I internalized quite a lot before verbalizing it. Apparently, wherever personality types come from, they start way back in childhood. My hunch is that at least some of it comes from internal structure and wiring, but I haven't really come across anything that supports my intuition.
Now, I truly am finished with the topic. It's time to cast my nets elsewhere.
