One day three girls were looking in te mirror. A blonde, brunette, and a redhead. And if you say the truth about yourself the mirror will grant you one wish. If you don't then yo will dissappear.
The readhead said "I think I am the most prettiest girl in the world" and poof, she dissapeared.
The brunette said "I think I am the smartest girl in the world" and poof, she dissappeared.
Then the blonde said "I think" and she dissappeared.
