A mom in New Jersey became furious when she saw the school assignment given to her 13-year-son that dealt with one-night-stand and herpes.

Amy Loper of Cumberland County told NBC10 that her eighth grader son at Myron L. Powell Elementary School in Cedarville, New Jersey, was given the following assignment:

"You had a really rotten day, but lucky for you your best friend is having an awesome party later. You go to the party and start drinking. You have a little too much to drink and start talking to this girl/guy you've never seen before. You head upstairs to get better acquainted despite several friends telling you that you don't even know this person. You end up having sex with this person. The next day you really can't remember everything that happened and rely on your best friend to fill you in. A week later you find out that you contracted herpes from your one-night stand and that this is a disease you will have all your life and never know when an outbreak will occur," the text read.

The assignment asked the student for his reactive response to the text.

"I was just shocked," Loper said.

It's part of a study guide the teacher made for the book "The 7 Habits of Highly Effective Teens," authored by Sean Covey and is marketed as a "handbook to self-esteem and success" for teens.

On Facebook, Loper wrote, "An assignment that was sent home today with eighth graders. Yes I've called ask parties I could to discuss. Needless to say this is ridiculous."

"I was told it's common core. Pervert at the school in recent years molested numerous kids. But let's say it's OK to drink and have unprotected one night stands. You have got to be out of your f$#&ing mind. And unfortunately I did use that word. Mind you this is a language arts assignment. And please no this isn't a surprise to the superintendent. I spoke to her myself," she added.

The superintendent told the mom that her son could opt out of sex education.

"But that's not the point," Loper said in her reply to the email. "My issue is with it outside of health class."

Parents were not told that the specific topics would be discussed, NBC10 said.

Loper said the assignment should have been more "age appropriate."
