An Alabama high school senior, Bryce Maine, wanted to take his grandmother to prom. She said “yes” and even bought a dress.

"She's never been to a prom so I figured, 'Why not take her?'" Maine said. "Every woman deserves to go to a prom, no matter how old you are."

But his school, Eufaula High School, has Dikembe Mutombo’d their plans.

The school says it feared allowing Maine’s grandmother to attend the prom would encourage other students to “make the school a mockery” and jokingly invite their grandparents.

Maine's cousin, Sarah Catherine, detailed the situation in a Facebook post Tuesday, and the story went viral.

The school’s policy is that prom attendees must be 20 years old or younger to prevent distribution of alcohol to underage students.

"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,” said Steve Hawkins, principal of Eufala City Schools, “We do not chance leaving any stone unturned when it comes to safety. Most high schools have an age limit for prom attendees."

Social media protested the situation using the hashtag #LetNannyGoToProm.

Don’t get too down about it, though, Nanny. Le’Veon Bell couldn’t go to prom either.
