That's Life

It's a phrase I've heard throughout my life-
Offered by friends, family and even enemies (depending on the circumstance.)
As I child, I HATED that short, but painfully truthful analysis of almost any situation:
Your best friend spreads a nasty rumor, "That's life."
Your dog gets hit by a car, "That's life."
Your second runner up in every category, "That's life."
However, when put into perspective, it is also a joyful reminder:
You published a book! "That's life."
You own a home. "That's life."
You sold a TV show!  That's me projecting... But I hope soon enough I'll be saying to myself, "That's life!"
Outlook is everything!
