Two.

You know how you have running jokes in your family?  Well, my sister and I saw a cartoon on Sesame Street or Electric Company or one of those shows once.  It was two little girls who were twins.   This is about how the it went:

Twin One: This is my sister.
Twin Two: This is MY sister.
Twin One: We have the same adorable freckles.
Twin Two: And the same mysterious green eyes.

I don't remember the rest of it, but Jennifer and I latched onto that part of it.  Of course, we have blue eyes, so it's a little different, but you get the gist.

Here's my latest - going in the mail to my beautiful, mysterious, adorably freckled sister today!

BTW - I m not happy about the green Sharpie border.  Apparently, that happened after the Ambien kicked in.
