The other Mammoths would whisper behind her back: "The herd would never survive if they let her stay with them", "she was ugly", her "bare skin" was "not even red", it was "pale", "greyish", "wrinkled". Her tusks were "too straight" no matter what rules one wanted to apply. And she was "small", "much too small" for a good mammoth. Simply put, they had to get rid of her. If they let her stay with them, she would probably just bring them into serious trouble. She was probably responsible for their dwindling numbers anyway.
Nobody ever had the guts to tell her all this directly. She knew what they thought, she knew of all the things said behind her back. She was okay with dying alone, somewhere in the south. She would just walk, until she reached the legendary deadly edge of the tundra, the "In die", she would then just let herself fall into the abyss into which all the "freak mammoths" before were sent. It was a place with no return, it was the dark and scary A-freaka...
They would forget about her as soon as they reached the forests in the north. She? she would never forget...
