Your father worked until midnight for several days in a row before coming home. He looked so exhausted that he just took off his leather shoes and fell on the sofa. Within a few seconds, you heard snoring. There was still heat in his shoes. He must have had a busy day on the soles of his feet. He didn't even have time to take off his socks, which had been on his feet for days. Maybe there is something you can do for your overworked father?
