dsp: And that's the very opposite to Christmas - when lots of letters (cards) are being delivered, not to a single address, but too all differant addresses.
100,000 letters to one address = one van full of post bags = time / postman/woman easy.
100,000 letters to 100,000 different addresses = very very time consuming.
So thanks for highlighting that - it's a combination of what a lack of education and not celebrating Christmas does.....
heehee...you are so cute.
You have left out a critical component of what is happening inside of those postal systems. You are only looking at the end point and have disregarded the postal networks that those letters arrive through. Think of how a toilet flushes...the swirl before it all disappears...or gets plugged and can't pass. And imagine that toilet not working very well to begin with
