Theory:

     One evening, when Taro and his parents were sitting in a corner of their hut, a strong wind began to blow. It whistled through the cracks of the hut and everyone felt very cold. Suddenly Taro’s father said, “I wish I had a cup of saké; it would warm me and do my old heart good.”
 
     This made Taro sadder than ever, for the heart-warming drink called saké was very expensive. ‘How do I  earn more money?’ he asked himself. ‘How do I get a little saké for my poor old father?’ He decided to work harder than before.
Explanation:

They were all sitting in the corner of their hut. The wind made everyone feel very cold. Taro's father was too old to bear the cold. He wished he had a cup of saké to warm himself. He also added that the saké would make him happy.

But Taro became very sad because he didn't have enough money to buy a drink called saké. It was very costly. He wanted to earn more money so that he would be able to buy it for his father. So, he decided to work harder than before.
