KFC employee resignation report

Dear Manager x: Thank you for taking the time to open my resignation letter!
I have been working at KFC for two years. I have gained a lot of valuable wealth in kfc. I have learned a lot about the world and enhanced my ability to do things for people, but these are not enough for me.
I am already 22 years old. Now I am a specialist in the adult college entrance examination. This means that I have to take down the specialist until I am 24 years old. My parents often talk to me about these things. They also want me to learn more. Written knowledge to enrich yourself, not to earn some tuition in KFC, while on the adult college entrance exam just for academic purposes.
Now think about the new semester, and I want to expand a lot, there is no extra time to come to the restaurant, so I want to resign.
24 years old, said that the big is really not big, but 24 years old, for a person who only has a college entrance examination and has no special skills, this is terrible, I have dropped too many things, I want to make up, so new At the beginning of the semester, many full-time schools are also enrolling students, and I have to sign up. So there is no extra time to work.
Thank you for your care during this time at KFC, but I’m sorry to say that after I resigned, I left Xiaolong and Xiaoming, and I didn’t mean what you meant to me, but if I don’t sign up for studying this year, If I have to delay the time of half a year, I really can't afford it.
I urge the x manager to forgive me for resigning as a KFC salesperson!
Sincerely, salute!
