I am writing this to you because I have something to inform you. Do you still remember the school transfer stuff we were talking last time? For the some reasons, it is hard to tell you on last thursday. Actually, “I suppose I have to make a transfer” is that what I really want to say.怎么把I am writing this to you because I have something to inform you和后面我要说的转学的事巧妙的联合在一块儿?而且语气要真诚,书写的方式要委婉和流露出尊敬
If you have made a decision, then you really dont have to be indirect. This is US, just say what you need to say. And be considerate, polite, but that doesnt mean you cant use direct language. Just say something like this.Hi, xxx: After much consideration, Ive decided to transfer to xxx. It has been a great time to work with you, and I really appreciate that. However, I feel that its in my best interest to transfer. (You may give a reason if you want to, but its unnecessary.) I wish you all the best for your work. Best regards,
