These are some passages from Man-Eating Cats by Haruki Murakami.
He'd been dead set against out marriage from the start, and his tone of voice said he'd finally been proved right.
He had taken a pair of scissors to every stitch of clothing she owned.
She had no idea where he had gone.
She and her husband had been high school sweet-hears.
It seems like the author decided to use contractions in some of the sentences and not to use them in others. I tried figuring out the pattern without much luck.
So this happens to me often. I can't figure out when to use contractions and when to use complete words.
Is there any rule for this? Or I just have to figure out what "sounds better"?
