For them, "I love you" was too luxurious (奢侈) When he was 14 working, my father had a bad temper. One day, my mother was 15 a quilt. I sat beside her and looked at her.

"Susan, don't worry about me," he said gently. "To tell you the truth, I just like 29 with your mom." Reading his eyes, I knew he 30 my mother a lot. | ||||
