Imagine that your character is alone in her family room, settled in for the evening. She’s reading a favorite book while watching a game show on television. Suddenly the doorbell rings.
What goes through her mind? Does she panic or react calmly? Was she expecting someone or is this a surprise?
Does she simply open the door or peek through a window?
What she does tells us a lot about her as a person. Some are brash and react without thinking. Some go cautiously throughout life, checking and rechecking every step along the way.
Your task is to write a scene in which the bell rings. Remember that however your character acts must be true to his or her personality.
Keep in mind that many times whoever is standing on the outside is a mystery person. That person could have benign interests or could be malevolent. You have to decide.
Have fun with this one.
