The 8-year-old from Chapel Hill, Tenn., lost her great-grandma, Minnie Sue Watts -- whom she called "Mawmaw" -- in August 2012, according to WSMV-TV. She says she knows Mawmaw is in heaven but still misses her everyday because she was her "favoritest grandmother ever."
In August this year, Bella honored Mawmaw by tying a note that read "Tell Mawmaw I love her" to a balloon and letting it drift up into the sky. Months later, a small box landed in the Hosfords' mailbox with a locket, deflated balloon and Bella's note with a response on the back reading: "Dearest Bella, Mawmaw is always with you. Just close your eyes and you will see her. Love, your guardian angel."
