When my mom and dad were first married, she had a horse accident that left her comatose for three days.
Her concussion was so bad that for many weeks, the folks had to live with his parents.
As it turned out, Dad's family did a lot to help their eldest son make a go in a number of things, babysitting grandchildren, having family dinners, and my mother asked Grandmother one day, "How can I ever pay you back for all you have done?"
My Grandmother said, "You can't. But, one day you will be able to help someone else, and I would expect that you would remember how you received help and reach out to help someone else."
