What do you think the deeper meaning of "Remember" by Christina Rossetti is?

Answer 1

It's about a person who dies and is gone ... but one always finds the real meaning of a poem in the final few lines, so in this case, the deeper meaning is that life goes on
"Better by far you should forget and smile
Than that you should remember and be sad."

In short, it's far better that we live our life everyday than it would be to sit around grieving for something and someone that we cannot change and is far, far away, in this case, in death.
