Urgh. Don't get me started.
1) Using first tense in a freakin' novel. Seeing this makes me wonder what people were taught (or not) in high school.
2) Not knowing how to use first-person point of view. Go read "The Catcher in the Rye", "To Kill a Mockingbird", "Jane Eyre". Read. And learn.
3) Describing the appearance of a character in one big paragraph. "She had this color of hair, this hairdo, this eye color. She chose to wear these ugly, old SpongeBob panties and matched them with her dumb, moth-eaten pyjama that she has since she is like nine or sh*t." It makes any writing look so immature. When you are over 15 and still write like that, it is time to change your personal library. While there still is time.
And now you wonder, looking at what seems like very stringent requirements to the mainstream, contemporary writer, what the hell do I read on a daily basis. Well, let me tell you I've been reading and rereading the same books for the last 10 years. And I plan to continue doing so.
