Before my 1st husband died, he told me this story:
His grandparents lived in England and decided to move to Canada. They bought tickets to ride on the Titanic. When it came close to the day to sail, grandma got sick and ended up in the hospital. She told grandpa to go on and she would take the next ship over. Grandpa went down to the ship. At the last possible minute, he knew he could not go without her. He went back to the hospital and after grandma got well, they took another ship. When they settled in Canada, they opened a little Mom and Pop store. They took their uncanceled tickets and hung them in a frame in the store. One night, after a few years, someone broke into the store and the only thing they took were those tickets. I doubt there is any way to prove any of this, but he swore it was a true story.
