In the Beatles' song 'All My Loving' I misheard 'I'll write home every day' as I'll ride home every day'.
I thought, why's he making such a fuss about being away if he can ride home every day? I imagined a cowboy or Pony Express rider singing the song.
Later when I learned that he was expecting to WRITE home every day, I still saw him on horseback, leaning a writing pad on trees and gates as he passed while riding a horse and writing a letter home at the same time.
