Shades of gray

I got my hair cut today. OK, it was sort of a haircut. Mandy, my "stylist," clipped the hair around my ears and shaved the hair on my neck. For me, that's a haircut. She confirmed what I thought: Much of my hair is coming back gray. Mandy said it is common for chemo patients to have their hair come back gray or red. It also would be common, she said, for my natural hair color to eventually come back. I just told her I was happy to have hair. "Chemo curl" is another possibly, but my hair is not long enough yet to know if it will curl. ...
My PET scan is a few hours away. It is the second most important scan I've had. The first was to determine whether or not my cancer had spread beyond my lung. It had not. This one is to determine if the radiation and chemo has killed the cancer. Please cross your fingers and pray it is dead. Thanks.
