"I understand the situation now, Grandma Zhang. Here's the thing, I haven't been going to the park to exercise these days, just been sleeping in at home. As for my mom's phone number, she changed it a year ago but didn't update it with the property management, so you couldn't reach us.
How about this, Grandma, maybe you can take down my number, so you can contact me in case there's anything in the future."
Lin Li explained to Zhang Fang after figuring it out.
As for exercising at home, mentioning these little details might lead to questions, so just saying I slept in is simpler.
"I guessed it might be like that. The security in our neighborhood... although we don't really have property management maintaining security, most of the folks here are good people. How could accidents happen so easily?
Old Zhou, he's probably just a bit too anxious, caring too much and kind of panicking due to worry, don't blame him for causing you trouble." Zhang Fang nodded and patted Lin Li's hand.
