Send a text message to the teacher during the holiday, ok?

1, if you change your name, please tell the teacher: I changed my name! Then say hello, the teacher should still know you.

2. If you send a text message to a junior high school teacher and he doesn't reply, you don't have to pay attention to him; If you sent a text message before and he didn't reply, you might as well send another one on holidays. Maybe he is not qualified to reply to text messages. Students send text messages to teachers, and teachers can't find anything wrong, can they?
