It’s Desi’s letter to Lucy:
Someday I’ll stop writing you letters.
Someday the spark we felt will diminish.
I wish I could pretend I never felt it.
I wish you weren’t my best friend, and that I never trusted you.
I think I’ll remember that feeling for the rest of my life.
No matter how many times you screamed, or threatened, or made fun of me to your friends.
Once two people existed, with love that could shake the Earth. And after that split second of perfection, we gave each other a Hell I hope other people never feel.
“I Love Lucy” was never just a title.
