Cynthia

Although John never really directly said that any of these songs were for Cynthia in interviews, listening to the lyrics there's a sort of hint that Cynthia is the inspiration. During the Beatles' touring years, it has been stated that John would have been homesick, missing his family which is evident during 1963-1965 in John's songwriting.
