You never know how a child will react when giving him or her a present.
Sometimes, she'll break into uncontrollable tears of happiness when faced with a new puppy.
Other times, she'll shock you with her adorable gratitude... even when receiving a large pair of men's underwear.
Such was the case when Jessi Eaton tried to prank her daughter with some tighty whities, writing on Reddit that the joke may have backfired - but in the most precious way imaginable.
"She has always been so happy with anything," Jessi says of her child. "This is the reaction she has for every gift she has ever received. She is an amazing little girl. I love her dearly and just wanted to share her pure and innocent heart with the world."
What a terrific video. And what a great message we all should take with us: appreciate everything you have, people.
