There are a lot of things writers do, and probably are unaware of the fact they're doing it. And the worse part is, it makes readers HATE you.
Don't force a situation in order to justify something that's already happened but before had no true reason for it. Readers pick up on this and aren't fooled by the patched up work you did.
Don't force dialogue in order to create a situation. Again, Readers pick up on this and they're not happy with you.
Don't force tension in order to create conflict. Forcing it, will give you a flat reaction. It will make the Reader actually stop reading your book. Create tension yes, but not in ways where it's unbelievable because it's SO predictable.
When I read something I want to feel emotion, (all kinds- pain, happiness, the butterflies, I want my heart to break when the MC's losing someone) I want to Love and Hate a person, (Like Snape in Harry Potter- Totally hated him as much as Harry did from book one to book six, Seven I was like Awww, why? then I liked Snape) Please show me a reason to care, and last give me some real conflict, tension, where I'm so drawn in I can't possibly pull out because it's actually in my head now.
What do you want when reading a story?
