If you want to join the party, you are going to talk to your teacher about what you should say and why you want to join the party. Don't say those empty words, it's too fake ~ ~ Help ~ ~

You can't just talk about joining the party. If you can join the party by talking about it, talk to the teacher. If you are a teacher and a student comes to you and tells you how I want to join the party, what do you think? That's disgusting! Just express your willingness to join the party, such as applying to join the party, and the rest depends on all aspects. How to behave depends on your understanding.
