95 'I can't do this'

Lina and Ning's maid carried boxes containing footwear inside Ning's house. A few minutes later, Lina walked into the lobby area, where Ning had been sitting and waiting for Lina.

Lina looked sad, pale and exhausted.  

As soon as Lina sat in the lobby, Ning started shouting at her. "Why are you so brainless? You could have asked any other person to carry these boxes to my house. Why can't you just stay with Wang?" yelled Ning.

"How can I refuse to take Mr. Wang's orders?" sighed Lina. Her voice and expression clearly showed that she was out of energy.

"I called you yesterday night. Why didn't you answer my calls?" Ning asked.

"I had taken some medicines for my foot pain. I think the medicines had sedation in them. I fell asleep very soon. I had no idea that the phone was ringing," Lina lied.

"I called you in the morning as well," pointed out Ning.
