What is this mordant obsession with mushed peanuts, fer gawds' sakes?! Well, in the UK a Jiffy bag is a quilted postal sack - something like an insulated airline sick bag, so I guess that works!

and yeah, that sounds like my dear bilingual UK too, belM :) If I go down to the builders' merchants (lumber yeard), I would probably ask for 4.2m of 2" by 1" and so on! The only exception I 've noticed to the personal weight thing is that gym freaks and body fascists sometimes refer to their weight in kilos. Mebbe they think it sounds more technical...
