A 6-year-old boy whose mom told him to keep his face mask on at school is now going viral for following his mom's instructions exactly.

Mason Peoples, a first-grade student in Las Vegas, Nevada, wore his face mask for his school photo.

The photo was shared on Facebook by his mom, Nicole Peoples, who wrote that her son had the option to take his mask off.

Peoples said her son declined and told the photographer, "No Thank you, I always listen to my mom!"

"I'm so proud of him for sticking to his word, but I should have been more clear about my rules on this day," Peoples wrote on Facebook.

While Peoples' photo of her son quickly went viral, Mason is not the only student who chose to keep a mask on for school photos this year, according to Matthew Comfort, branch manager for Dorian Studio, the photography studio that took Mason's school photo.

"We've taken hundreds and hundreds of students this fall wearing their masks," Comfort told "Good Morning America." "It's not an isolated incident."

Comfort said that Dorian Studio first asks schools if they want to give students the option to remove their mask for their school photo. If the school allows masks to be removed for the photo, then the photographer gives each student the option.

The photographer who took Mason's school photo on Sept. 7th, followed the guidelines correctly in giving Mason the option to take off his mask and then in following his request to leave it on, according to Comfort.

"If students don't want to [remove their mask] because of safety concerns, we don't push them," she said. "[The photographer] did exactly what she was supposed to do."

Mason's now-viral school photo with his mask on is a sign of the times, as it is now the third school year in a row upended by the coronavirus pandemic.

Both the Centers for Disease Control and Prevention and the American Academy of Pediatrics recommend that face masks be worn at schools by both vaccinated and unvaccinated people.
