Ives argues that the style of the letter and its mature handwriting prove that Anne must have been about thirteen at the time of its composition, while Warnicke argues that the numerous misspellings and grammar errors show that the letter was written by a child.
Ives hævder, at stilen og håndskriften i brevet tyder på, at Anne var omkring 13, mens Warnicke påstår, at stavefejlene og de grammatiske formuleringer typer på, at det var skrevet af et barn.
