Today is random acts of kindness day.
It's the 10th anniversary of the day in New Zealand, which encourages people to do something kind for a stranger without expecting anything in return.
Organisers say the day started after co-founder Josh de Jong was stuck in Auckland traffic and watched "some irate drivers ahead of him getting into a bit of a road rage stoush".
"He began to think, 'What would it be like if on one day every one in New Zealand was kind to a stranger?'"
September 1st was chosen as it's the first day of spring.
