Oh, what a lucky sock it was

Dear Half of Lucky Pair of Socks,

It is with the utmost pain and remorse that I write you, for it seems your life partner, Other Half of Lucky Pair of Socks, has disappeared. I fear the worst.

I will do everything in my power to find your mate, but if I'm unsuccessful, please know you will always have a safe home in my drawer.

Sincerely,
Rock and Roll Grammarian
