We're not crying, you're crying.

A little boy's heartbreaking tribute to his late little sister has struck a chord with people across the globe. Alex Deasis, 4, was filmed playing Remember Me from the animated movie Coco to a photograph of his sibling on what would have been her first birthday. His dad Samir shared the emotional footage on Twitter, where it captured hearts across the globe. The heartbreaking lyrics include "though I have to travel far, remember me. For even if I'm far away, I hold you in my heart." https://twitter.com/SAM1R/status/947291512303489024 His dad wrote on social media:

"My son singing "Remember Me" from the movie "Coco" to his baby sister, Ava, who we lost this past May. "He's only 4 years old and he understands. He didn't even know he was being recorded. He just wanted to sing to her for her 1st birthday!"

The video has gotten more than 1.83 million views since it was first shared on social media. Four-month-old Ava Lynn died in May 2017 after she was diagnosed with the kidney condition hydronephrosis, according to MySA.com. Samir told how the couple were "brought to tears" by the support they had gotten since he first shared the video. He added:

"All this ugly in the world and these kinds of things make it still seem beautiful in the dark times. "All these blessings for our small family make us very humbled and thankful and blessed."
