And here's something interesting. Maybe ironic, not sure what word to use.
Both of our sons have an auto-immune disorder called alopecia areata, which involves hair loss. The oldest son went bald at the age of four, the younger at the age of ten. And they both have the most extreme version, alopecia areata universalis, meaning no hair of any kind whatsoever: no eyebrows, eyelashes, arm or leg hair. When they were little, people would look at them and think, "Oh, no! Cancer, chemotherapy." In reality, they were the healthiest kids ever. But I remember many times being out in public with one, or both, and seeing people check them out and then look at me with enormous sympathy, and I could see them thinking, "Oh, that poor woman. Two of them!" And I couldn't help but kind of laugh or giggle, because there was absolutely nothing wrong with them, just that they were different because of the alopecia.
The other interesting thing about having a couple of totally bald kids, is that I sometimes got special treatment. Such as being upgraded to first class seats on a flight. Again, I'm sure the gate agents took one look at those two little bald boys, and thought, cancer, two of them. I did not turn down the upgrades.
