REMEMBER, this isn’t meeting the author of the character, it is meeting the person they created. Think about how their character would react to meeting your character in a certain situation. You are also responsible for writing the situation in which they meet. Maybe, they are both spies meeting to exchange information. Maybe they are both starting school the same day and find that they have all the same classes. You can choose any situation you like for them to meet but make sure you are creating a conversation that those two characters would have.
Enjoy this, it doesn’t have to be serious but it must make sense and have proper punctuation! Think quotation marks!
