Wood later shared that she dedicated the song to her 3-year-old son whom she had with ex Jamie Bell.

“There’s been multiple times now, my son has woken up and found me in the living room, having watched the news all night, and I am quietly weeping,” she explains. “He doesn’t know hate. He hasn’t been taught it yet. He is pure and full of hope.”
