A nun's headgear.
I had a Church of England education. As long as one avoided the attentions of the choirmaster and had an endless capacity for tea and cake it was moderately congenial. I found the lack of rigid dogma agreeable, particularly the fact that a belief in God was not actually necessary.
Religious observance usually took the form of stirring story about triumph over adversity in a benighted colony or an entirely random parable followed by the observation...
" ...and that's very much like our Lord Jesus, isn't it"?
Then a link so tenuous and arcane that the congregation of schoolboys was reduced to patholigical boredom and breath holding contests. Occasionally there was an uplifting hymn but always sung to some appalling new tune which went heavy on tambourines but avoided any unseemly taint of high church.
So my experience of nuns was, perforce, limited.
