As you are walking along an unfamiliar street, have you ever wondered about the life there? Are the occupants behind the walls living contentedly or perhaps praying hard for a change that seems impossible? Where are the children? Will they be out for some fun and games in the late afternoon? Laughing gleefully and chattering away in high spirit or will there only be quiet whispers in the air? If you knock on the doors, are you going to be invited in or being left standing outside and ignored?
