The Little Things
Ask some simple questions about your character. These may not seem important, but they help you get to know your character and can be a good reference later on (I love knowing that for a hot drink, my MC prefers tea with lemon. I’ve used that several times.)
How does your character respond to hello?
What is your character’s favorite dessert? Meal?
Does he prefer tea or coffee or neither? How does he take it?
What is her idea of a fun Friday night?
Does he have any hobbies?
What kind of music does she listen to?
