Initially, Grace wanted to pass her house key to Heinz so that he could sleep upstairs. However, she was afraid that he would still be asleep when she returned from grocery shopping. If that happened, she would not be able to enter the house. So, she decided to bring Heinz up first before going to the store.
That was why she didn't pass the key to him.
Heinz took a deep glance at Grace and then got out of the car.
His legs were a little numb, so he staggered and almost fell.
Grace supported him quickly and asked, "What's wrong?"
"My legs are numb," he replied in a hoarse and tired voice.
The strong scent of cigarettes encased him.
"Let me help you," Grace said. "Walk slowly."
He grunted in reply and shifted his body weight onto Grace. When he smelled the faint fragrance on her, his heart warmed.
"When did you arrive?" Grace asked him again.
"Half-past four," Heinz said. "It was too late. I was afraid that you would be sleeping, so I didn't go up."
