and all is wasted in the sand think hourglass > like breaking diamonds with your hand idk what the writer meant by this but given its placement in the song it makes me think of how she's as likely to break diamonds with her hand as she is to forget this person.. the river is her love and the memories are like diamonds">
I don't think this song's really about suicide, since it keeps reiterating "I remember" and I mean if it is, then it'd have to be a ghost story or something (not impossible, mind you)
The song is clearly about some emotional experience and the memories tied to it I think it's about the memories of someone she loved dearly
