There's the barista who made the coffee, the guard at the front desk of the office building, the delivery person bringing lunch for a staff meeting, there's the executive that's late for her meeting and impatiently pushing the elevator button. That's not even all the people that would be in one scene of a busy office building.
Which leads to this week's writing prompt.
Now describe this person. What do they look like? How do they hold themselves? Are they a disabled person? Acknowledge the disability, but don't make it their only descriptor. Describe their skin tone using colors instead of food. Hair color, length, texture. How old are they? Voice, accent, scent; dig into the details.
