Buy the ice

Once a simpleton's wife told him to buy some ice.

Two hours later, he didn't come back. She wanted to know why he didn't come back and went out to have a look. She saw he was standing in the sun at the gate and watching the ice melting. 

"What's the matter?" She asked him. "Why don't you bring it in?"

"I saw the ice was wet and I was afraid that you would scold me so I’m running it dry." The simpleton（傻子，笨蛋） answered.
