If you mean “below”, the missing part is likely a fictional continuation. Here’s a satisfying ending:
Writing
The next morning, I carried the broken mixer back across the grass.
Denise opened the door and immediately frowned.
“I told you. You need to replace that thing.”
“I agree,” I said. “But before I do, I want you to see something.”
I held up my phone.

“I’ve been too polite,” I told her. “That’s my mistake. Starting today, you don’t borrow anything from me again.”
Her mouth dropped open.
“You’re seriously going to ruin our relationship over a mixer?”
“No, Denise.”
I looked at the cream-colored machine in my hands.
“You ruined that relationship when you decided my things—and my mother’s memory—weren’t worth respecting.”
She eventually paid for the repair.
And I never lent her another thing.
A few weeks later, the mixer came home.
It wasn’t perfect. The repair had left a tiny scratch along the side.
But when I plugged it in, the familiar hum
