Writing in first person is sort of fun because you feel more like you are telling a story to a friend.
A cool breeze blew across the slit of my pantalets. I inhaled sharply in response to my exposure to the night air, as well as a stranger, in such a manner. His hand cracked down on my barely covered backside. I gasped with the impact.
“I bet that did not feel like a spanking from an old lady.” The cocksure gentleman adjusted my torso for a better angle and landed another swat on my bottom.
“I do not know what you people here call a spanking, but my grandmother spanks harder than that.”
Why could I never learn my lesson?
I think it also helps the reader to identify (and hopefully like) the heroine (or the point of view character).
There's also the question of the reliability of the person telling the story.
I straightened my skirts and patted my hair in preparation for my new dance partner. The bully was gone, along with my thoughts of him.
As we approached the dance floor, the bitter widow squinted at my coiffure and tsked in dismay. “Honestly, Sarah, how did you manage to get your hair into such a frazzle already?”
There was no way to explain to her how hanging upside down over a man’s knee made it challenging to maintain one’s hairstyle, so I was grateful when she took her attention away from me to focus it on our hostess, Lady Waterford who presented my next partner.
Notice the word "bitter" describing Mrs. White (Sarah's nemesis). An editor highlighted that word and said "We don't have any proof that she's bitter."
I thought about the comment a bit and decided to leave the word in. Whether there is proof that she's bitter or not, Sarah, the storyteller, believes she is and that's what matters.
How do you feel about stories written in first person?
