Neither snow nor rain nor heat...

In the afternoon, Granddad sits by the kitchen window watching the road.

He's waiting for the mail to come.

When the mail truck pulls up, Granddad is off. Thunderstorm?

So what!
Like the ancient Persian couriers that Herodotus described:
"Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds"
(are you impressed, David?)
Of course we think of the mailman when we say it, as it has become associated with the USPS
but it could easily be said of Granddad.

Bringing up the mail is the highpoint of many of his days.
