These are the four d's that dominate the thinking about kids like mine, kids like sweet M.
If they are damaged—poisoned by some environmental toxin—then someone is to blame, someone has to pay, and something must be done.

If they are disabled—unable to function as "normal" folks do—then we may seek reasonable accommodations.
And if they are different, simply different, there is space for the other four d's that I prefer: daring, determined, delightful, darling . . .
