So many people enter our lives. Some become permanent fixtures, some stay with us for awhile, and others just pass through. But what about those we see every day but know little about. Our neighbor Nancy fits into that category. She and her sister moved into the house behind ours probably about fifteen or twenty years ago, yet I know so little about them. All I know is that Nancy is a widow, a former teacher, a caring sister and a woman who loves to garden. I see her out my back window--where my laptop is located--every day that the weather allows. She always wears a hat and often has a rake, a hoe, pruning shears, a watering can, or a shovel in her hands. I suspect this activity has given her special pleasure since her sister has been ill with Parkinson's. When I stopped to talk to her yesterday, Nancy said that her sister had moved into a nursing home in April. There is now such sadness in her eyes.
