Water comes from the clouds and drenches the ground, it doesn't care where it falls. The sun draws up the water into the clouds and they go where the wind takes them. There are no borders for the clouds, only places to go. Mountains catch them and sometimes collect the water they bring and send it down when the sun melts the ice and snow. When children dance in a puddle, they did not ask it from where it came, they only know that it is wet and fun to play in. The water cascades down on all people, regardless of who they are. It washes away the mud and the dirt and renews the earth and helps plants to grow. It wets everyone equally, yes the rain falls on us all.
