from MISS BRILL (1920)
~ by Katherine Mansfield
On MY way home, `I` usually bought a slice of honey cake at the bakers. It was MY every Sunday treat. Sometimes there was an almond in MY slice, sometimes not. It made a great difference. If there was an almond it was like carrying home a tiny present -- a surprise -- something that might very well not have been there. `I` hurried on the almond Sundays and struck the match for the kettle in quite a dashing way.
But today `I` passed the baker’s by, climbed the stairs, went into the little dark room -- MY room is like a cupboard -- and sat down on the red eiderdown. `I` sat there for a long time. The box that the fur came from was on the bed. `I` unclasped the necklet quickly; quickly, without looking, laid it inside. "But when `I` put the lid on `I` thought `I` heard something crying."
Note: The last line is copied incorrectly.
The correct line is:
> "But when she put the lid on SHE thought she heard something crying."
The first-person point of view is this:
> "But when `I` put the lid on `I` thought `I` heard something crying."
Note: When I changed "she" to "I," I marked the I's like this -- `I` -- so you would not miss them. Counting the corrected last line, there are 8 instances of the word `I`.
I made the other changes in ALL CAPS so you would not miss those either.
Best wishes in your studies.
