Girl performing '600 acts of kindness' in memory of grandmother

LAKEWOOD, Wash. -- An 8-year-old in Washington state is celebrating her late grandmother's memory with 600 acts of kindness to others.

Alex's story began in September 2013, when her grandmother Linda died on what would have been her 60th birthday, according to The News Tribune. Instead of mourning, Alex and her mom decided to celebrate Linda's life with 60 acts of kindness to others.

Alex's mom says they donated various things and left a big tip for a waitress and ended the day by going on a toy shopping spree for St. Jude's Children's Hospital.

"I try to do acts of kindness at home, but they don't count," Alex told the Tribune. "You have to do them for someone you don't know, or as a surprise for someone you do know, like one of your teachers."

For the past several months, they've documented their acts of kindness on Instagram using the hashtag #forlinda. Coming up on this March 22, Alex and Sarah will have shared 600 acts of kindness with the world.

"I'm always amazed by her heart," Alex's mom Sarah said. "I look at her spirit of giving to others and think, 'If an 8-year-old can do this, why can't anyone?' "
