congratulation.. what you're experiencing is quite rare.. a purely incidental insight and a temporary self-aware flash into your own cognition, IROC it.. but fret not it will pass shortly.. that "wee pattern" you've just consciously noted.. is merely your minute thought process.. going through it's breif motions.. i've witnessed it myself.. it's quite something.. provided you don't blink..
First time ever was when I went into grade 7, I started to hear them but didn't say them until grade 8.
It was 1978.....I was 6. I called my sister a B!xtch. Dont ask me where I learned it from. It had to be from one of the teens in the house at the time. She gave me a butt whipping as my mom looked on.
I think I was about 10 or so. My Dad never cursed much, and I still have never heard my mother curse.. I had friends that would curse, but only occasionally. Then my grandmother started paying me to sit with my grandfather who had Parkinson's, and do little chores for him. My cousin lived with them and had a CB radio in his car. I learned to really curse from his CB radio buddies.
