Rachel Uretsky-Pratt is an elementary school teacher in Kennewick, Washington, so this time of year she gets a lot of gifts from students: chocolates, notes, jewelry.

But one stood out to her so much that she took a picture and put it up on social media. The gifts are especially meaningful to her, she said, because many of her students’ families struggle financially.

She explained: “With it being the day before break and Christmas right around the corner, most teachers bring their kiddos something such as books or little treats and occasionally in return receive something from their students,” she wrote on Facebook on Wednesday. “Today I received some chocolates, sweet handmade notes, some jewelry, but these Lucky Charm marshmallows stood out to me the most.”

All of her students, including the one who gave her the Lucky Charms, get a free breakfast every school day, she said, as well as a free or reduced-price lunch.

“This kiddo wanted to get me something so badly, but had nothing to give,” she wrote.

“So rather than give me nothing, this student opened up her free breakfast cereal this morning, took the packaging of her spork, straw, and napkin, and finally took the time to take every marshmallow out of her cereal to put in a bag-for me.”

Because, she said, everybody knows the marshmallows are the sweetest part.

Uretsky-Pratt, 24, who is in her second year of teaching, said she was touched by the girl’s gift, one of many heartfelt holiday presents from her students.

“All my kiddos are super sweet and giving,” she said. “Kids are naturally kind and loving. The world kind of hardens us sometimes.”
