Relativity

This was a favorite joke of my brother's friend High School best friend Dave .

Outside of the States, a Yankee is someone from the United States

Inside the U.S., a Yankee is someone born North of the Mason-Dixon Line*

If you were born North of the Mason-Dixon Line, a Yankee is someone from New England

If you're a New Englander, a Yankee is someone from Maine

If you were born in Maine, a Yankee is someone who eats pie for breakfast.

To my Maine reader: Jess, if you read this, perhaps you can address its accuracy.

* For my foreign readers, The Mason-Dixon Line divides the North from the South, pretty much reflecting the divisions in the Civil War.
