When her grandmother's health began to get worse in the fall, Mary would make the drive fr

om Washington, DC to Winchester, Virginia, every few days. To make the trip to the hospital, Mary had to get on highway 81. It was here that she discovered a surprising bit of beauty during one of her trips. Along the middle of the highway, there were a long stretch of wild flowers. They were beautiful and almost poetic（诗意的）in appearance. The first time she saw the flowers, Mary was seized by an urge（冲动）to pull over. She then stopped her car and picked a bunch from the soil. She carried them into her grandmother's room when she arrived at the hospital and placed them in a glass by her bed. For a moment her grandmother seemed better than usual. She thanked Mary for the flowers, commented on their beauty and asked where she had gotten them. Mary was filled with joy because of the flowers' seeming ability to wake something up inside her sick grandmother. Afterwards, Mary would pick a bunch of flowers on her way to visit grandma. Each time Mary placed the flowers in the glass, her grandmother's eyes would light up, and they would have a splendid conversation. One morning in late October, Mary got a call that her grandmother had taken a turn for the worse. Mary was in such a hurry to get to her grandmother that she drove past her flower spot. She decided to turn around. She headed several miles back and got a bunch. Mary arrived at the hospital to find her grandmother very weak and unresponsive（无应答的）.She placed the flowers in the glass and sat down to hold her grandmother's hand. She felt a press on her fingers.
