When it fits: Choose this wording when the meaning above fits what you intend to say. Give the reader enough surrounding context to follow the example; if clarity matters more than the shorthand, use the plain-English wording instead.
When to avoid: Avoid assuming that a label reveals somebody’s motives or private behavior. If you are unsure how your words will be understood, explain the situation directly and ask a clarifying question rather than relying on the expression alone.
