I got a letter in the mail today
from the wife of my grandfather.
Grandpa enjoyed your call
We are looking forward to seeing you over Christmas.
I called my grandfather on Monday
the words between us vibrating rapidly through the air.
This reply circled back to me by Thursday
traveling overland, thousands of miles.
I wonder if he remembers the call by now, over all that distance?
