Ok, tell us a flat fact?

I dunno....I asked because flat and fact start with an f;)))

All the F words .. gotchu ;) I got to crash :/ I'll be offline for few days but I'll check in next week and catch up with you :) I know you don't celebrate Christmas.... but hopefully you get some time off cos off. Happy holidays, talk soon :)

Merry Christmas dear ..Happy holidays and come back soon..gonna miss you;))

Hmm;))

Geographic fact...flat...yes;))

You might say that. 

An optical flat is a precisely polished flat surface, used as a reference against which the flatness of an unknown surface may be compared. It can measure the flatness of a surface in millionths of an inch.

Now that info is so optically factual;))

Yes, it is.  I've done it myself ... created and checked surfaces that were flat with .00005 (50 millionths of an inch).
To give you an idea of just how big that is:  The average human hair is .003 in diameter(3 thousandths of an inch).  Now cut that hair into 60 equal pieces and you'll have a rough idea of how big .00005 is.

OMG ALF....WOW!

Air isn't free in London either?  It sure isn't here anymore!

Not since I can remember.....if you need to pump up two tyres you have to pay twice.......That's real inflation for you....:(

You have given a flattened ...answer...it is so flattering;))

Yes...flat fact...;))

So true...Livvie;))
