The teacher suddenly received an invitation from a pupil. Do you want to go?

First of all, the student I have taught is a teacher-student relationship. Although I haven't contacted you for many years, he is your student and sends you an invitation in person, which shows that he respects you very much.

Secondly, the student's parents invite you to his wedding, and it is possible that you are the one who keeps up appearances for him.

Also, you don't need a few hundred dollars in gift money, so that you won't appear that the teacher is so inhuman in Oketa.

Therefore, it is necessary for students to invite their teachers to the wedding.
