"She told me that she didn't want to be counted absent, and that she didn't want to miss any work," Curry said of her daughter. "She not only helped our family out, but returned to her responsibility at school."
The teacher was unfazed by Stiles’ small guest, Curry said.
The mom, who said the photo "made (her) heart want to explode," soon shared the image on her own Facebook page, where it received thousands of reactions and was shared across the social media platform.
"I'm not sure on the legalities here or what kind of rules were broken but I also just don't care," Curry wrote in the Facebook post. "My sweet teenager helped her family out and returned to her other responsibility while snuggling her baby brother.
“I'm either the worst mom in the world or totally nailing it. Please don't tell me which one. Let me live in ignorant bliss while I stare at this picture.
“Life is short. These are the moments that make it so incredibly sweet.”
Curry told ABC News that the photo showed her that despite the 14-year age difference between the two siblings, they still have a close bond.
"The fact that he is sleeping so comfortably on her in the middle of a class full of teenagers tells me how much he trusts her," Curry said. "As a mom, it makes me so thankful that they have this kind of relationship, and I pray it will always stay that way."
