The Power of Delightful Surprises
When I was a little kid we used to make May Baskets and leave them for our neighbors on May 1.
If you're not familiar with the tradition, you make a paper cone and fill it with flowers to leave on someone's porch or doorstep. The really fun part is that it's a secret - you ring the bell and run away so that the person who answers the door only sees the flowers.
I loved hiding around the corner waiting for the door to open and see the happy smiles on my neighbors' faces.
