This song was written for Nico's living mother, which could either mean for the living memory of her real mother or her aunt, whom she considered a second mother. Nico felt a lot of guilt around the time of her mother's death as she had pretty much abandond her mother before this and this guilt can be felt in the words of the lyrics and her delivery of the song. This was likely her way of showing her aunt how appreciative she was of the help she gave to her mother.
