James Joyce's Ulysses: why "wrote" and not "write"? [closed]
Your second quotation is from a letter by Martha, writing to Bloom. It is a deliberate typo by the author, meant to show that the character Martha wasn't a good speller or typist. See, e.g. Newman & Thornton Joyce's Ulysses: The Larger Perspective.
Bloom is making reference to this very error when he then says "Wonder did she wrote it herself."
Some editions of Ulysses unfortunately correct one or both of these deliberate errors, thereby ruining the joke.
