200-249-"You two sure get along great! It looks like you are having fun being together! You seem bright and cheerful!"
150-199-"You're starting to get to be friends. Just maybe, walking along the same path has made you understand one another."
100-149-"You still have room for improvement. How nice! I mean, you can become even better friends!"
50-99-"You aren't getting along, are you? It's glaring at you with a look that's kinda scary."
