who are not required to 'remember' my newer Box # VS older, after the now several years since the change;
they could ... just return an item with Addressad unbekannt [sp?]--yet they do! 'correct', every time.

(I had a chance to get Box 666 last year!--one minion remembered my comment way-back--I reconsidered, reminding him of all their extra work last switch, despite my not-quite-100% efforts to correct all the slackers.)

But the clincher for me is: same guy plays a mean/make that, mellifluous baritone horn, noted when he (+ his own cohorts) serenaded us all (Xmas carols or similar festive occasion.)
A competent brass choir at your local USPS?

Priceless! With extra Brownie points: no guitars or other electric paraphernalia in their ensemble.
Such things ameliorate mightily when the center clearly-cannot-hold, most everywhere else.
