Many thanks,Aristophanes!(if you knew,by the way,how much of Ar. I had to read in the original when I was young...)My -- in both senses of the word--ORIGINAL interpretation of the phrase (i.e.going slow)was based on our experience here in France of the very tardy delivery by UPS of goods ordered,say,from amazon.uk---but then I presume UPS is not USPS--or is it?In which cases I almost went postal myself...
