While traveling for work, a local woman has been giving homemade cards to strangers who might need a pick-me-up at the Houston airport.

"I just want somebody's day to be better," Catharine Knight told CBS News. "I really just want to make the world a better place."

Flyer Heidi Botkin was flying solo with her three kids when Knight approached her. "I was super stressed," she said. "So, yeah, that [card] was a nice little pick-me-up."

While travelers are being uplifted by these friendly cards more than ever during the pandemic, spreading random acts of kindness isn't a new thing for Knight.

She and her son Parker have been writing messages for strangers for three years now.

To date they've written 25,000 notes to uplift others.
