"Daughter is a spoiled brat and doesn't deserve these tickets," Bjerke said on a post written at the Fargo/Moorhead online garage sale Facebook page, where she had also offered the tickets up for sale. The tickets for the Aug 23. concert at the Fargodome, were worth around $110 , but Bjerke chose to undersell the pair for $90. It is unclear what sort of behavior prompted the punishment, and Bjerke has chosen not to disclose this information.

"It's not just that humiliating people, of any age, is a nasty and disrespectful way of treating them, It's that, humiliation, like other forms of punishment is counterproductive.
