Sue Johnston has been used to getting flowers from her husband John for 46 years. Every Valentine's Day he would send her flowers with a note that said “My love for you grows.” But John died a couple of years ago. Last year, she got flowers with a note signed by someone named John. She thought it was a cruel joke. But she called the florist who told her it was no mistake. It seems John prepaid for several years with instructions to send his wife a special gift on Valentine's Day. See what the last card says.
