"Grandma, please wait here for me at the hospital while I go home to tell Auntie Du what happened. We've been out since early morning and haven't gone back yet. Auntie Du's probably worried."
Ye Tianxin felt that since Auntie Du had kindly let them stay at her place, the least they could do, as a matter of courtesy, was inform her that they planned to stay out for the night.
"That's right, Tianxin. You're very thoughtful. Let's do that. Take a cab home and let Auntie Du know. Don't worry about me. I'll wait here at the hospital and won't wander about."
"Grandma, just watch some TV. I'll bring us a change of clothes and my practice books."
Ye Tianxin was reluctant to leave her grandmother on her own at the hospital, but she really needed to go home and, since she didn't have a phone, she had no way of keeping Auntie Du informed about what was going on.
After Ye Tianxin left, Grandma retrieved Lu Jijun's business card and looked at it a few times.
