Hmmmm, you remind me of a letter sent by me to a friend of mine in 1993 & never arrived.
When do the math & based on my P.O. "tremendous" shipping service:
2011 - 1993 = 18 years!
Since Worldwide P.Os Shipping Time Frame for "Undelivered" letter is standardized, I think I'll be having to wait a "little" bit for another 10 years!
