I am writing this application for quitting the club for you with extremely complicated feelings. I am honored to join this club and get the opportunity to exercise. I came to the choir with passion and love for singing. After an interview and examination, I was fortunate to be a member of the club. I'm sorry that my personal ability is insufficient and I don't understand. Although I like the choir, I regret that I chose to quit, although the construction time is not long. I still want to thank you for taking care of me during this period. I won't forget that I quit the club not only because of my lack of personal ability, but also because I was too busy with personal affairs and often asked for leave, so I chose to quit. Time flies, a week has passed, and I also know the importance of the cooperative spirit of a successful club. Getting along with the members also made me feel the warmth of the group.
