Pedantry, Richard ~~ I should not, thou wouldst not, he would not...

Probably an obsolescent rule, [Fowler had much to say about it] ~~ but you surely will realise the difference between 'I should not' [conditional] & 'I should not [= 'it ill becomes me to do so'.]

Bet I can out-pedant you any time you choose, matey! My pedantry, as a correspondent remarked on another forum, is 'legendary'.

~M~

In fact, I don't think I am actually a pedant in any meaningful sense: I simply aim to operate on the principle that accuracy matters.
