I’m not sure ‘bout your ‘thousands of pieces’; much has gone the way of ‘paper-less’.
‘Bout the only thing I still get in the mail...is JUNK.
I suppose you’d have to see it then. More mail than you realize goes through the main post offices, including the junk, but they also process and handle UPS items.
And then there are stubborn folks like me who will always get their bills and financial statement via snail mail.
I do gripe about the junk, though, mostly because it takes up room in my garbage bags and then I have to pay someone to haul it off.
