Margaret wrote a note and put it an envelope. She wrote Molly’s name on the envelope and placed it on the hall table. Next to her picture. Then, she wiped a tear and opened the front door. She would not see her sister for several weeks. Margaret knew going away to college would be difficult. Especially when she thought about missing her family. Closing the door behind her. She took a deep breath. Her father was waiting in the car. She tried to think about future visits with her family. She smiled. How exciting that will be. When she gets to see her little sister again.
