My father, who had been away on a business trip, would come back. I missed him too much that I couldn't wait to seeing him at once. My father's trains would arrive at 5:30. To my surprised, Father gave me the call at 5: 00. He told me not to meet him at the train station because the heavy rain. Therefore, I didn't listen to him. Though it was raining cats and dogs, but I went to the train station. The moment we caught sight of each other, all of us were very excited and I hug my father warmly and tightly.
