"We have always been and always will be friends. That in itself is a tremendous thing." - A.A. Milne and E.B. White
Houston was designing new Spiritiles in his workshop when his first-born son wandered in to see what he was doing. He saw the elephants Spiritile design, loved it (he loves animals!), and asked if he could give it to his soon-to-be-born baby brother.
“Of course,” Houston said. “In fact, you can give him this very first one.” It was only fitting that the Spiritile be named: 'Sterling,' the nickname Houston's oldest son gave to his soon-to-be-born baby brother.
The story is a mixing of two quotes - the left side from A.A. Milne, the right side from E.B. White, combined to show the efforts of two becoming one.
