This is Mr. ABC.  DEF's flex time (study hall) teacher.  I have had to warn your son multiple times about his talking out and not listening to my directions to get into his seat and stop talking.  Unfortunately, today he did not heed my warnings.  I told him he was going to get a detention if he did not stop.  He did not stop.

I am sending the detention slip home with him today.  His detention is assigned for Tuesday.  He is to bring the slip signed back to school Tuesday morning.  Please have him here by 7:25 dropped off in front of the school.  A teacher will get him in the lobby.

Any questions, please let me know.

老师比较怒了，今晚得跟臭小子上课！！！

另外，校长说健身房的小纸条，校长太落伍了，现在大家都用那啥软件约那啥，谁还写小纸条呢，校长你得与时具进啊！
