It may seem counter-intuitive, but most of us don't walk correctly. It's not our fault, and it's not our parent's fault.

Yet, despite my earnest attempts otherwise, it was also the type of song writing that not many people seemed to be taking much notice of.
When siblings Audrey and Jack DuCharme are healthy, they need a breathing treatment each day.
