In Whose Service Are We?

Several years ago, Grandma offered to bring dinner into a family in our ward whose mother was sick. She drove to the house and knocked on the door holding her box lid full of hot dinner items. A family member she didn't recognize, opened the door and invited her in. She was directed to the kitchen and she set down the box. As she started to tell them about the dinner, she was startled to see that she didn't know this family! She excused herself, taking dinner with her and saying that she was sorry, she had the wrong house! How disappointed the "wrong" family must have been to have missed out on a home cooked, home delivered, free meal!
