How to euphemistically refuse the enrollment of vocational high school teachers by sending text messages

Dude, you're just like me. Those people are extremely annoying. If you want to say euphemistic messages, I suggest you not send them. You must express your ideas clearly. I won't bother you if I don't go. The more tactful you are, the more he will feel that there is still a chance and will come to you. To put it mildly: Teacher, the major I am interested in is not that (the major of their school), so I may not be able to go to your school. Thank you, teacher. Tough: Teacher, I don't want to go to your school. Needless to say, please don't bother me in the future!
