How about I got a bad hair cut so I steered my step-sister toward that stylist!
Why would you do such a terrible thing to anyone?
I'm interested in watching my sister's reaction after the haircut
You shouldn't lie about that capabilities of people. You're just asking trouble with your sister.
I'm going to tell my sister that is not a big deal, it's just a bad hair cut.
It will be a big deal to your sister, as it will affect the way she feels. You should not lie about yout stylist. Your sister may not trust you again because of this.
