退出晚间创意写作课程Withdrawing from evening creative writing course

Dear Mr. Carter, I am writing to inform you of my intention to withdraw from your creative writing course. It is with great reluctance that I have made this choice, and I would like to explain why I must do it. For the past year, I have been working long hours at my regular job as a copywriter. I began your creative writing course because I was bored with the dull tasks assigned to me by my boss and I hoped to gain the skills needed to move into writing fiction. Alas, although I have learned a lot on your course, I have no choice but to withdraw. I had not anticipated just how difficult it would be to juggle a full-time job and a part-time course. I work from nine in the morning to six in the evening, and then I am in your classes from seven ‘til nine. This means that when I get home, I am utterly exhausted and unable to do any sort of writing, creative or otherwise. It is just not sustainable. I hope that next year I may be able to enrol once again in your fascinating classes. I might be able to find a new job in the winter that would allow me to work shorter hours, giving me a better chance to appreciate your evening lessons. If so, I will sign up again next year. Until then, I wish you all the best. Sincerely, David Wills
