60th Anniversary

Today would've been Mom and Dad's anniversary if they were still alive.
They got married sixty years ago today on September the 25th of 1965.
Today is also the anniversary of my sister-in-law and brother.
Back in 2013, I had to say goodbye to my father and mother.
After living for six and a half decades, Mom and Dad passed away.
If they hadn't died, they would've been married sixty years today.
