A simple act can be powerful.

It's what we've learned over more than five years of Random Acts of Kindness. When people are surprised with something nice, they smile, they cry, they laugh. They are changed.

Some of our random acts are just that: random. We arm our crews with umbrellas on a rainy day, hand warmers in winter, free coffee on a Monday. We also take your nominations and work with our Help Desk to surprise your friends and neighbors. Check out the results. They're pretty amazing.

We need your help to continue an 11Alive tradition. Every year, on the week leading up to Mother's Day, we focus our Random Acts of Kindness on moms.

Nominate your mom NOW, and join us May 5-9 to celebrate our moms.
