It is one of the few times in my life I have ever felt guilty for letting someone down.And it was the person that I was the closest to — my mother.I was visiting her in Lincoln in March of 2006 when my older brother had to make a run to a pharmacy in Roseville. We went with him.We stayed in the SUV when Richard went inside. The second Richard had shut the door and started to walk away Mom told me she had something important to ask me.She was afraid when the time came that my other two brothers and sister — who saw her everyday as they resided in Lincoln — wouldn’t follow her wishes.
