Why? Because I am so NOT a visual person. If I'm reading a book, and there's a long description in it, I usually skip right over that part. I just can't picture it in my mind's eye, and my thoughts start to wander. Plus, I would much rather get to the action and the dialogue.
Needless to say, that is a problem as a writer. People want to "see" what they are reading, so it is something I work on. I just finished reading The Nightingale by Kristin Hannah. It's fabulous, and so are her descriptions. Here's one about the night from Chapter 17:
"Night had fallen. With the blackout shades and unlit streetlamps, the street was dark as a cave. Cars rumbled past, unseen without their headlamps on; heard and smelled but invisible unless an errant bit of moonlight caught them."
Damn! I would have written "it's dark out" and that would have been that. Yep, definitely something I need to work on.
