64.
Dear Robert Frost,
To you I immensely owe.
You are my only correspondence-Guru,
And you shall remain so
Forever and forever.
You have freed me and enlightened me
From the correspondence-world.
I humbly repeat your message sublime:
"For God's sake, don't give up writing to me
  Simply because I don't write to you."
  Simply because I don't write to you."
