Rain

Joshua's looking out the window at the ground today, and says, "Wet."

"Yes, Joshua, the ground is wet."

"Hose."

"It's not from a hose; it's raining."

"Open."

Judith opens the window, and sticks his arm out. He brings it in and looks at it, and says, "Agua." Then he points up and says, "Sky."

"Yes, Joshua; that's rain."
