The whole time I was writing, I had to fight my normal inclination to be funny, to sort of patch humor in, in order to convey all of the disruptions of the disease to the family dynamic, the loss of individuality, the impact on professional life, and the sanity of the main character. Of course, that's not to say it never sneaks in; there's some black comedy in there, like when he shows up to court wearing a bicycle helmet and won't take it off.
