Lyn is aware of the tragedy in Boston.
Her biggest question was "What is a marathon?" Mom decided to focus the conversation on the definition of a marathon. Lyn was very confused about it. She couldn't understand that the athletes would train all year to run many more miles than Lyn could understand yesterday. She was unable to equate the marathon to when she used to race for Special Olympics.
She corrected Mom on her terminology. Lyn insists she raced in the 2 feet and 4 feet races instead of the 200 and 400 meter races. That's OK. Mom can be wrong. At least she remembered that she used to race.
Mom worked hard last night to keep the television turned to entertainment shows and avoid any special updates or news on the tragedy. It would have caused more confusion and tears.
