Only people of a certain age will remember or relate to what a real letter is or was. I don't mean those "appeal" letters,chain letters or flyers posted on lamp-posts searching for a lost Fido. It could have been one from Grandma on your birthday.Perhaps the two crisp folded dollar bills made the letter more interesting. A real personal letter was something you could read over & over again. I remember, while in the sixth grade, the class had an assignment to write a letter to an imaginary friend. What a dumb idea, I thought, writing about yourself to a complete stranger.
