Growing up I never really believed in the whole "Jehover, angels, Jebus, spirits, etc" thing. I just went along with everyone because I knew I would be rejected and shunned if I said that I did not believe.
Over time I learned certain "instincts" that allowed me to live among the "faithful" without their catching on to my non-belief. One of my instincts that I learned was to expect to bow my head at the beginning and end of any "meeting". It literally became an unconscious reflex.
Now, six years after leaving the bOrg, I find that reflex still showing up every now and then. Granted, not as often as it used to, but it is still there. The other day at work we were about to have our usual weekly group meeting, and as it began I felt the "bow your head" reflex start to kick in... and I literally had to make a conscious effort to keep my head up.
This is a sure sigh of just how programmed people get when they are part of the "Organization". I am still working on deprogramming myself.
