A female boxer has one special feature: she can grow as tall as she wants

A female boxer has one special feature: she can grow as tall as she wants. She entered a boxing match and made herself three times taller than her own. Her opponent, a man, was scared. The woman is very short, even taller. Her opponent is not a child. The man should not be a woman boxer. She grows so tall that the man reaches her kneecaps. Don't change characters. When a woman sees a man, she laughs because of his height.
