Charlotte dies with Daniel by her side

Daniel tells Charlotte about his conversation with Desmond at the Swan Station door. After a coughing fit, Charlotte slips to another time in her mind and says "I'm not allowed to have chocolate before dinner." Charlotte dies right after saying that. Daniel weeps by her side in an incredibly emotional performance.

Is there any significance to Charlotte's last words, or was she just revisiting a random time in her life just before her death?
