You're looking sane today

This entirely gratuitous little book is an explanation of sanity for those who need it and an excuse for sanity for those trying to avoid issues. It's invaluable as a gift, alternative to sex and as something to give people who've read R. D. Laing's Knots. Also contains a healthy recommendation to read other books if you don't understand the foreword/forewarning. Not to be taken internally, whatever the provocation.
