A secret code helped 81-year-old Cynthia Riggs and 90-year-old Howard Attebery find love.
Riggs told CBS News Friday that she and Attebery met 60 years ago while working together at a marine laboratory in San Diego. They often passed notes using a secret code in which A = B, B = C, and so on.
Although Attebery liked Riggs, he never asked her out since she didn't feel the same way. They parted ways, married other people and both eventually divorced.
Then, at the age of 90, Attebery decided to tell Riggs how he really felt. He mailed a note to her home in Massachusetts that said only, "Cynner, I have never stopped loving you. Haward xx" in their secret code.
There was no return address, but Riggs knew exactly who it was from. She tracked Attebery down, and within an hour, they were engaged. They married last month.
