The scarlet "S" stamped on the back,

Gives me joy to see in the mail,

With curves and swirls of the dark black pen,

They tint the envelope pale.

I carefully open, so as not to disturb,

The squished little ruby of red,

With it's bubbles and drips of crimson,

I have so many times over-read.

With a ruby on the outside,

What could it contain?

Other precious gems,

Of quality the same?
