Seventeen-year-old Stiles Parish is the older sister of four adorable little ones. Providing a helping hand to her parents when they need it definitely isn't a new thing for her. And when her 3-year-old brother James needed to be picked up from school -- but their parents, Candice and Brandon, were unable to get him themseves -- she stepped up in an epic way.

Stiles left school early to retrieve her brother, but instead of taking him home, she decided to head back to school with him in tow so that she wouldn't miss any of her classes.

"I thought she took him home until I saw her Snapchat," said mom Candice Curry in a Facebook post.

After only a few minutes, the little boy promptly fell asleep in his sister's lap, prompting a classmate to take what may just be the most adorable photo of all time.

We're sure James's presence was a bit of a shock to the rest of the students at first, but as Candice told ABC News, "[Stiles's] teacher was very supportive and didn't mind him being in class at all. He slept most of the time and if he had become a problem my daughter would have taken him out so that she didn't disrupt other students. She attends an amazing school that clearly sees the value in family and education."

What happened with James and Stiles is definitely an unusual circumstance, and while we're sure the little one won't be attending any more high school classes for a while, we're really glad that he'll have this amazing memory to look back on and share with his awesome big sis.

As Candice said in a continuation of her Facebook post, "Life is short. These are the moments that make it so incredibly sweet."
