Snowflakes dancing in the sky, it was an awfully cold winter. Mary felt as gray as the sky outside. She struggled to get by the tough winter because her bills went up while her income went down.
Her refrigerator sat empty. Her only food consisted of peanut butter, bread and bananas, only enough for two sandwiches. Worse still, it would be four days before she got paid. As Mary prepared to sit down and eat half of her remaining food, she heard a knock at the door. Who could it be on such a freezing night? Robbery scenes from films flashed across her mind. Then Mary shook her head and laughed at her foolish thought-no robber would choose her as a target. Opening the door, she saw a stranger standing outside, body trembling with cold.
"Madam, sorry to disturb you, but I'm lost and get stuck in the snow. Could you please spare a piece of bread?" the stranger asked cautiously and politely in a weak but deep voice.
"I'm afraid not," said Mary, "but I could make you a peanut butter and banana sandwich."
"That sounds wonderful," the stranger answered. "Mind if I wait here on the porch?"
"Yes, I do mind," Mary replied, "but you could come in and eat it at the table."
Not expecting both food and warmth, the stranger entered the house eagerly. Mary hurried off to the kitchen for the last four pieces of bread, peanut butter, and bananas. In a few minutes, she returned and invited him to sit down to eat what she could offer. After eating, the man thanked and said goodbye to her.
Looking outside, Mary hesitated a moment and said, "If you don't mind, you can sleep on the sofa." "That would be good enough," responded the man gratefully.
Mary went into her room, and locked the door. The next morning, when she woke up, she remembered the man. "How will I tell him I have nothing for breakfast?" she asked herself. She dressed, unlocked, and opened the door slightly.
To her surprise, the man was nowhere to be seen. ……
Mary opened the envelope and found a letter.
