Possible plot hole question
After 20yr old Daisy returned from New York and Benjamin returned from war, she seemed to have forgotten Benjamin upon first seeing him and it took a second before it dawned on her who he was. She later tells Benjamin that her grandmother had died so if she wasn't there to see Benjamin and her grandmother was dead, what was she doing staying there at an "old folks" home?
