In business writing, "you-attitude" is a style which emphasizes the perspective of the reader instead of the writer, whereas "me-attitude" is the opposite. For instance, a request for a refund might be met with a response such as:
I have have arranged for a refund to be processed this afternoon. (me-attitude)
Alternatively, the writer could say:
You will receive a refund in your bank account by Thursday at the latest. (you-attitude)
The first response emphasizes what the writer has done and when, a matter of little interest to the reader, who is concerned with when they will receive the refund.
Your memo should begin with a brief description of the task in hand. Depending on the memorandum template you have been accustomed to using, this will be something like:
Dear X, You asked me to identify three sentences in business communications that do not use "you-attitude," and, in each case, to identify why this is the case, and to rewrite the sentence employing "you-attitude."
Some possible examples could include corporate publications, which might say something like: "Bartlett's Bank has a long history of providing bespoke financial services to high net worth individuals." This emphasizes the bank and its history, rather than what it can offer the client. It might be rewritten as follows: "All your needs as a high net worth individual will be promptly, courteously, and efficiently met by the well-trained professionals at Bartlett's Bank."
Another example might also come from an e-mail communication: "We will be reviewing applications and reaching a decision on Tuesday afternoon." This focuses on what the employer will be doing, not what the applicant has to do. It might be rewritten as: "Please ensure that you submit your application by 12 noon on Tuesday."
Examples of "me" versus "you" attitudes can also be found in academia; one example might be the following: "Kingston University is demanding, and only accepts the very best." This emphasizes the attributes of the university, not what is required from students. It might be expressed using you-attitude in the following terms: "If you have a GPA over 3.5, and are a clear, critical thinker, Kingston University may be for you."
You might then conclude with a sentence or two pinpointing why the you-attitude examples are better, for instance, because of greater precision, warmth, or customer focus.
