The bear is not nice. The mouse chases the bear. The tiger does not chase the bear. If someone chases the mouse then they do not chase the bear. If someone chases the bear then they visit the bear. Round people are nice. If someone chases the bear and they visit the bear then they are round. If someone chases the bear and the bear needs the tiger then they do not visit the mouse. If someone is blue and they do not visit the tiger then they are round.
The bear does not visit the bear.
