‘Strange man’ as in I didn’t know him, rather than ‘strange’ as in weird. Somehow I don’t think that makes it any better.
A couple of weekends ago, I did something that was more stupid than strange. I paid good money to investigate ancient limestone caves in the Forest of Dean (that’s in Gloucestershire, for those who are geographically challenged and even fail to negotiate Milton Keynes’ roundabouts). They had been mined for iron and ochre (clay deposits containing ferric oxide) for centuries if not millennia. Small amounts of coal continue to be mined locally – don’t tell the eco-nuts or they’ll glue themselves to the mine shafts … actually, DO tell the eco-nuts and leave them there.
