--------------------------------
The adjuration to be "normal" seems shockingly repellent to me; I see
neither hope nor comfort in sinking to that low level. I think it is
ignorance that makes people think of abnormality only with horror and allows
them to remain undismayed at the proximity of "normal" to average and
mediocre. For surely anyone who achieves anything is, essentially, abnormal.
