A University of Central Florida student has been suspended for two semesters for grading and posting a letter of apology sent from his ex-girlfriend onto Twitter back in February, and she doesn't even attend the school.

Nicholas Lutz, who posted the tweet that has been retweeted almost 122,000 times and receives over 338,000 likes, included four pictures of the handwritten letter marked up in red pen to make grammatical and spelling corrections. He gave his ex-girlfriend a D-minus (61/100) and wrote his explanation before sending it back.

According to ABC affiliate WFTV9, Lutz's ex-girlfriend filed a cyberbullying report with the Volusia County Sheriff’s Office, but prosecutors never pursued the claim. Instead, Lutz received a letter from UCF saying he was suspended for two semesters for violating two rules in the university's code of conduct: disruption and cyberbullying.

"If they can do that to me, it can happen to almost anybody. That’s upsetting," Lutz said, noting that he's appealing the university's decision.

Lutz's lawyer, Jacob Stuart, calls the suspension a violation of his First Amendment rights.

"That should really, fundamentally, concern people. Not only those who are students, but people who believe in the idea of freedom of expression," Stuart said.

"My main goal was never to expose her. It was to show the emphasis on the letter," Lutz continued. "Looking back at it now, it’s probably the craziest thing that will ever happen in my life."

In the letter, Lutz docked points from his ex on her introduction and conclusion as well as not providing proof to back up her strong hypothesis of never cheating on him. In the end, Lutz wrote, "Revision for half credit will be accepted. Good luck."
