Let us all take that as definitive. Sorted!

How about a quick hands-up for the 'not-sures'?

Can I put half a hands-up for maybe?

Is that an absolutely positive definite maybe, snorgle?

I'm in the not-quite-so-sure-that-this-is-so-cut-and-dried-as-gil-seems-to-think-it-is group, myself. I think.

The generally-in-agreement word-perfect linguistically-dual Betws-y-Coed cottage-dwellers say no.

[CdM] Why not found the-try-to-take-the-concept-to-a-logical-though-somewhat-absurdist-extreme-or-at-least-to-the-level-to-which-one-can-be-fussed-to-do-in-the-next-minute-or-so-provided-the-attention-span-lasts-and-one-doesn't-get-confused-by-the-lack-of-commas-or-other-such-things-such-as-the-fact-I've-pretty-much-forgotten-where-I-was-ah-yes-the-absurdist-extremes-that's-the-one group? More fun!

...and besides flights of fancy, I'd say no.

How is the weather today where you are?

Sunny with occasional cloud, and really quite warm.

Forty Nine Degrees Farenheight, chance of snow tonight.

Moroni, that's chilly. What country are you in?

85°F in my office. Blazing sunshine, central heating.

Central heating? Fools. Don't you use centigrade yet?

USA but I am originally from the UK.

Even with centigrade central heating is sometimes necessary.

I prefer to heat with Fahrenheit. It's hotter.

Kelvin is the hottest, zero is tricky though.

Absolutely! Absolute zero, easily defined. Tricky to find.
