Those names in your class (Goodness, Mercy etc.) sound like gipsy/traveller ones. I taught a Lightning from that community.
A test I have failed: our head thought it wise for staff to learn first aid. After a course on one evening per week for several weeks I failed the practical - apparently I would have killed someone with my resuscitation method.
I did help my wife with the 1991 census in quite a rough area and it was very difficult collecting the last few forms from the secretive and the recalcitrant. We certainly had to leave some households to be persuaded by a higher authority.
'While': I know someone who was brought up in Lincolnshire. He uses 'I'll be there while nine o'clock' meaning 'by' or 'at'. I think he can also use it to mean 'until'.
'Whilst' sounds antiquated to me, but I prefer it to the hideous 'unbeknownst'.
While I'm here: someone on another site was pulled up (I thought correctly) for writing 'rising to a crescendo...'. However, another pointed out that dictionaries have crescendo meaning 'high point' as well as 'increasing in loudness', so I've always been mistaken.
Rather arrogantly I disagree with the dictionaries, given the Latin root of the word.
