In the past we have talked about including the five senses when detailing your scene, especially if you’re having trouble setting it. However, not every person in this world has access to all five, and neither should every single one of your characters if you’re hoping to make them more realistic as well as diverse.
Write a scene in which your character is sitting back and observing the world from the center or the outskirts of a very active setting. Only this time, take one of those common senses away. How will this experience of observing the world differ for someone who is blind? How will it differ for someone who is deaf? Maybe a character who lost their sense of taste is taken to a fancy restaurant, or you can explore different possibilities for a scene with a character who has hypoesthesia.
Be careful with this one: make sure to do some research first, and try to put more focus on the senses that are there instead of whichever one you choose to exclude.
