I agree, I think they would've been. Have you ever read Adonais? It's the poem which Mary Shelley reportedly wrapped her husband's heart in. Percy wrote it as an elegy for John Keats—when he died, he even had a book of Keats' poems on his body. Towards the end of the poem, he talks about when he might meet Adonais/Keats in the afterlife, and there's this beautiful line... Let me find it.

The soft sky smiles, the low wind whispers near:
'Tis Adonais calls! oh, hasten thither,
No more let Life divide what Death can join together.

Oh, I love Frankenstein! It's a fascinating story, and Mary Shelley was our age when she wrote it. She had such talent for evoking... I don't know to describe it. Empathy, I suppose. It makes you feel the pain of Frankenstein's creation so acutely... Why are you asking?
