Just sign your name! How amazing it is to eat bread! But you should educate your children not to eat in class, which will affect their study and violate discipline! Let the children write sincerely on the self-criticism book (more words, more neatness, and promise not to do it again)! Don't worry, it's nothing compared to falling in love, reading novels, fighting and cursing teachers with mobile phones! However, be respectful to the teacher!
