Let’s let the holidays guide our writing. The scene is Christmas day. Write a scene of a family gathering. Use the present tense and focus on describing action. Whether the scene is opening presents, or eating a holiday meal, or any other holiday tradition, depict it using descriptions of your characters’ physicality, and setting. That means their holiday sweater and the hutch that holds the china.
Include some dialogue. Note: You can use internal thought, but only sparingly, and only around the central conflict.
Maybe your characters don’t celebrate a holiday, then use that as your premise, depicting what they do instead and the way the cultural prominence of Christmas colors their activities.
