Thingking about how frail she had gottten. Though i didn't really know exactly what words to use. I finally took courage and asked,"Grandma, how do you handle being confined to a wheelchair? When you were always so active?" She thought for an instant. Then she said, "Getting old is not for sissies. Not even for people who are not sissies. Especially if you have lost your health mobility. But, as long as i have my mind,i can enjoy something every day. For instance, your visit right now. It's such fun to hear about your college life. Particularly the classes you are taking and the friends you are making". What she was really telling me was that people have to make the best of their situation. Which is true at any age. Not just when you're old. I felt inspired by her attitude.
