Aliensouldream, I am so pleased you stopped by. This is such a fine piece, dedicated to such fine characters. But you have said it better, why it is threaded through with the sadness of loss yet is not sorrowful:

"Their life together was unplanned and yet it was the saving of them both, a daily gift. The ache of separation is the measure of that love. But there is no loss here. Frodo sees, hears and feels with and for Bilbo still."

Thank you so much for this eloquent and perceptive comment, ASD. :)
