[Tuj] How about a hedge trimmer?

What it comes down to is that "less" applies to continuous quantities, where "fewer" applies to discrete quantities. So you have less water but fewer glasses. "More" applies to both, just because English is such a wonderfully rich and evocative language (which is more agreeable than saying it is an inconsistent mongrel of a language).

(Dunx) Dead right; you tell 'em. (the second phrase should be delivered in an aggressive N. Ireland accent). There are other pairs of words that have this distinction, eg "so much" and "so many". So much bollocks (speech by Blair), or so many bollocks (field full of bulls).

Back from hols and I'm moist. "You'll love camping" I said to NotmrsBobthedog. "The weather is always good in Cornwall this time of year". As we dismantled the tent in a gale with rain heavier than I've ever ever seen it I reconsidered my enthusiasm for fresh air and natural elements.

Post script
Two days after we returned home I asked Notmrs if she'd like to go camping again next year. She said yes. We are planning to go to Scotland. I wonder if she is seeking revenge?

Btd] You weren't near Boscastle at all, were you...?
