Hardest day of my life was having to tell my grandmother that it was unsafe for her to be behind the wheel of the car. She nearly collided with a 3/4 ton pickup truck on the open road, and ran into two people in town. Was reported by three individuals. Highway Patrolman came out and helped me explain to her what might've happend.
She simply refused. The patrolman ended up taking away her drivers license, and I've had to hide her keys.
I understand. This grandmother probably diapered your bottom at one time and here you are having to do this. Driving is such a major symbol of their independence. Most of us will be there one day and hope someone in my family will be brave enough to take my keys. :o)
