You can write the memo in either the first or third person. Depending on the objective of the note, either of these can be utilized. Most memos should be between three and five paragraphs long, with each paragraph including three to five sentences. Memos are intended to be brief reminders. As such, there is no requirement that you use formal language or avoid colloquialisms when writing them. When writing in the first person, you are referring to yourself in the present tense. For example, if you were to write "I like to eat ice cream after school," you would be using the present simple verb form "like." In general, verbs in the present simple form will work well for first-person memos because they are plain and straightforward. You may want to include specific dates or times, so using the present simple makes this easy to do. Writing in the third person refers to someone else, usually a company or organization. Using the third person keeps the memo formal and concise while still being readable by others. If you were to write the same memo in first person, it might sound like you're sending it directly to someone's employer or office manager, which isn't appropriate behavior for a memo. There are two types of third-person memos: direct and indirect. With a direct third-person memo, the writer identifies themselves as the sender without any hint of ambiguity.
