I take umbrage with the term "snail mail". It is an insult to the hard working blue collar workers of the United States of America Postal Service. In a society whereby much is valued by speed, the USPS handles tangible items that require care & accuracy, of which most workers appreciate. That it is slow & steady and under the auspices of Congress, one might be more respectful of hard working employees. They are not the 1% sitting in comfortable offices gloating at the physical labor of others. The USPS touches every address in the US. Other delivery services "don't go there." The USPS binds the nation & is Constitutionally mandated.
Alas, I don't have a smartphone, so I will never know "the truth."
