IDK Fran.
I more or less just woke up, and decided not to go back to sleep.
At the time, one of the neighbors across the street was plowing his driveway, and there was a yellow flashing light in the window, and I looked out to see what it was (could be a county snow plow going by too) and check the snowfall and I guess all that activity caused me to ....stay awake and not roll back over.
So, just "stuff worked that way".
