Going through [1] the pile of snail mail I find that my mortgage company never received my last payment. In the seven years I've been sending in my mortgage payment (to three different companies; curse those corporate mergers!), I've never had one lost on me, until now.
And here I thought that U. S. mail was sacrosinct—that it would always arrive and never be lost. That the U. S. Postal carrier would keep his appointed rounds through rain, snow or dead of night.
