An Alabama high school is worried a super-senior will turn its prom into a drunken rager.

Catherine Maine had never been to a prom before, so she asked her 18-year-old grandson Bryce if she could go with him, according to Al.com

But Eufaula High School shot down the idea, and said the granny wasn’t welcome, because she could possibly give alcohol to the minors attending the dance, the site reported.

Her grandson has now decided to stay home for the night and his classmates are rallying behind him with a #LetGrannyGoToProm campaign circulating on social media platforms.

“My blood is boiling right now,” relative Sarah Catherine said in a Facebook post. “My little cousin Bryce wanted to take our Grandma to his senior Prom since she has never been. Well after she done bought her dress and made plans, the principal decided that they cannot do that anymore… Like really?! Eufaula High School let my Grandma go to Prom!”

The school defended its decision.

“Safety of students and staff is the first and most important of the many tasks of a school administrator. For the 10 years I have been high school principal, we have denied requests each year from students asking to bring older dates to prom,” Principal Steve Hawkins said in a statement to WVTM.

He continued: ” We do not chance leaving any stone unturned when it comes to safety. Most high schools have an age limit for prom attendees.”

This isn’t the first time a loving grandson wanted to bring their bubbe to prom.

An Indiana student asked to bring his 93-year-old great-grandma to the big dance in 2015, according to NBC.

The school apparently granted him a “special exemption to take a date over age 21” and the two “shuffled right along” with the rest of the kids.

No alcohol-related incidents were reported during that shindig.
