In the video, Bailey seems to fully understand what Abby was singing—the final time she would be serenading her closest friend. As a result of Bailey’s failing kidney, she died shortly after.

Thousands of people from all over the world shared, liked, and commented on the video when it was put online, praising Abby and leaving supportive comments.

After watching the video, thousands of people send Abby presents and cards in the hopes that they will cheer her up, according to News.com.au.

Abby’s mother used the occasion to express her gratitude to everyone who sent cards and sincere comments during their time of mourning. She said that the kindness the family received from complete strangers gave her a glimmer of hope for the future, particularly in light of how much hatred is circulated online.

Although it is heartbreaking to witness, it is also comforting to know that Bailey spent her last moments in a caring environment.
