Pieces of Friendship

I am a puzzle piece
Full of angles and edges
Fitting perfectly next your piece
Your ends fitting with my beginnings
I am an edge piece 
Because I'm always looking ahead
Outside the puzzle.
You are a center piece
Because you are surrounded by others
And and the subject of the picture
Always and forever.
Sometimes other pieces are squished next to us
But they never fit quite right as you and I fit.
Of all the puzzles in the world
In the 206 countries,
7 continents
50 states,
5 oceans
How lucky am I that we ended up in the same place?

(For my best friend because she's awesome and beautiful, inside and out. I love you so much.)
