Ghawi's mother Sandy Phillips said her daughter texted her from the theater: "[She] texted, 'Mom go get some sleep, get some rest, I'm so excited about your visit next week. I need my mama.' And I wrote back and said, 'I need my baby girl.'"
Ghawi had narrowly escaped a shoot-out at a Toronto food court last month that killed one person.
"She had an epiphany at the moment that it could happen to any of us at any time and instead of being afraid of that she embraced life even more fully," Phillips said.
