Wildfire

Each year, actress Whoopi Goldberg, co-hosts 'Comic Relief' to aid her country's homeless people. This is one among the many projects that she is involved in.

She says :
I fear waking up one morning and finding out that my life was all for nothing.
We are here for a reason. I believe a bit of the reason is to throw little torches out to reach people through the darkness.

When you are kind to someone in trouble, you hope that they remember and are kind to someone else and so on. Soon, it will be like a wildfire and spread itself around.
