A New Hampshire mother says she's outraged after her 13-year-old daughter was suspended for a posting on Facebook, wmur.com reports.

Kimberly Dell'isola of Concord, N.H., said her daughter was suspended for five days after posting on Facebook that she wished Usama bin Laden killed her math teacher, according to the website.

The mother reportedly agrees that the post was wrong, but called her daughter's suspension from Rundlett Middle School too harsh.

"In hindsight, she's mortified that she said that, but she's a 13-year-old kid," Dell'isola told the website. "You are denying her an education based on something she did at home. That's my business, not your business."
