Here’s a polished continuation of your line in a smooth storytelling style:
“That’s what my daughter Emily told me one Thursday as I was slipping on my shoes after visiting my granddaughter Olivia.
Her voice was calm, but something in it made me pause.
‘Mom… I need to tell you something,’ she said again, quieter this time.
I looked up at her, already sensing that this wasn’t going to be a simple conversation.
Emily never spoke in half-sentences unless something was weighing on her.”
If you want, I can continue the story with a twist (family secret, emotional reveal, or dramatic event).
