Of all the books I've read, the general plot is usually what's left in my memory as time goes by. I sometimes remember the various characters if their traits has been extensively explored in the story, but seldom I remember specific sentences.
In the book I'm reading at the moment, there's a passage that stroke me.
I don't why but I'm pretty sure this will stay in my memory for awhile.
"A poor black cat had been mistaken for coals and shovelled on the fire"
it's a Virginia Woolf novel.
