The act of father-in-law

I was curious and stupid. But recently I came to school. Because he was waiting for his father-in-law who was hungry for his home. One day father-in-law fathered his school to communicate with his parents. A father-in-law who does not stop while mother is home. My homeroom teacher visits home because he doesn't come to school. I would like to thank the teacher who worries about me...
