Paul, just curious...does your sister want to cover her face, or is it someone else's idea?
The reason I ask is the comfort factor. When I ventured out in public for the first time after surgery, I was a mess...over 450 stitches in my face, a large wound on my forearm, a bigger one on my leg, and all at the beginning of summer, so temperatures were quite warm.
I opted to go "uncovered" as much as I was permitted to. No bandages on my face, and minimal protection on my arm and leg. It was simply too uncomfortable for me, and I sort of felt that if anyone took issue with the way I looked, it was a problem that I didn't have to share with them.
I was quite surprised all in all. No one reacted inappropriately, and I was much more comfortable physically that I would have been heavily bandaged.
I wasn't trying for shock value nor sympathy, and received neither. Empathy, yes...shock, no.
Just food for thought. I know that women are much more sensitive in that regard ( I wasn't beautiful to begin with ;^) but she may want to think about the comfort issue a bit as well.
BTW, please pass along to her my best wishes for her return to health, and congratulations on being the Mom of a bright young man. He's going to be incredibly proud to have her there!
