Unexpected gifts bring strangers joy

Hundreds of unsuspecting people got a pleasant surprise when they were approached by strangers on the street. Instead of asking for something, these people had something to give away for free: two bouquets of flowers. The only catch? Keep one and give the second bouquet away in order to keep spreading more kindness.

The kindness campaign was called 'Petal it Forward,' and was created by the Society of American Florists.

Florists from from every state participated, giving away flowers on the street, in offices, and anywhere they could spread love.
