Read the following anecdote and identify the prepositional phrases:
Nathaniel Hawthorne's son, Julian, was also a writer, and father and son were frequently mistaken for each other. "Oh, Mr Hawthorne, I've just read The Scarlet Letter, and I think it's a real masterpiece," gushed a lady to whom Julian Hawthorne had just been introduced. "Oh, that," said Julian, shrugging modestly, "that was written when I was only four years old."
