Group for those who are Introverted and those of us who are Loners. Someone who doesn't need other people around them to validate their own existence.
Hi James and thanks for the comment.
If a loner and ex-introvert may suggest something, search on "Children Learn What They Live" by Dorothy Law Nolte.
Her line "When children live with ridicule, they learn to be shy" spoke to me.
Ms. Nolte omitted and I added the line "When children live with violence, they learn to be fearful."
