I have lost family on Christmas day. Not this year, actually a couple of decades ago. My grandmother and her son, my uncle were driving home on Christmas day. It was dusk and she exited an off ramp. However, earlier in the day an 18 wheeler with mechanical problems had parked on that off ramp and failed to leave any lights or indication of any kind that would allow one to see it in the dark.
My uncle was killed instantly. My grandmother (still going strong at 96 years old) was peeled up off of the highway and had to be given an artificial hip was left with a knee that no doctor would even consider touching and had to have her scalp grafted back to the top of her head.
Needles to say, my grandmother is one tough old bird!
