Good question! I never take the chance to think about it—or pay attention. Maybe morally grey characters? I like writing flawed and strange characters, too. They can be perfect (from the outside), but they are a little coo-coo bananas in the head. It definitely helps with world-building, or just how the characters will interact. I guess those traits spark joy in me. (˵¯͒〰¯͒˵)
