Can it be? to live forever!

I feel like this story really came together after me knowing that Mary Shelley outlived her husband and her two children. Although this story is about a husband taking care of his wife on her death bed then her dying he started wondering if he is immortal. Mary Shelley had to bury her husband and her two children. After all these family members of hers died definiately her children she was starting to wonder too if she is immortal. The majority of mother's dont ever think that their children will die before them and definitely not two of her children. As all these people start dying she wonders if she is immortal meaning she cant die. A line in her story states "For Ever! Can it be? to live for ever!". I believe she was wondering why is everyone else around her dying besides herself, leading her to believe she is immortal.
