This is lovely, sad and sweet, @alheath. Goodbyes are hard, even when they are necessary and important. I don't know whether Lily and Florence are sisters, room mates, lovers, or friends, but you've done such a nice job of writing this in a way that shows it is a difficult parting for them both.
Thank you! They're daughter and... a kind of mother. Lily lives in a children's home, which is run by Florence.
