I've read the "On writing" and other valuable positions. I've learnt all about unnecessary adverbs and repetitions. I can make words of my characters sound strong and natural.
Whereas most of writing guides I encountered focus on making dialogue less dull I'm afraid I went too far in the opposite direction.
The conversations I write seem too intense and short. It's almost like a punchline in response to a punchline in response to a punchline. Every sentence coming out of my heroes mouth is a strong statement conveying a lot about themselves, their opinion and decisions.
Single lines seem interesting, quotable and probably would do just fine in movies. But I aspire to write books and my guts tell me I should work on this matter. While reading my dialogues I have a feeling, that they are a bit exhausting. A reader needs to absorb a lot of information fast. The dramatic change happens during two pages scene and it's just too rapid. In the end the conversations as a whole seem a bit unnatural because no one in real life exchange ideas at such a rate.
The whole thing reminds me of a time before I learnt the "show not tell" rule. Then I also produced too little text for an action presented. I have practiced and now am satisfied with a length of my stories. Unfortunately it doesn't exceed to dialogues in particular.
Let me give you an example. The following scene takes place in a plane between a stewardess and a young man. I got rid of all the bits.
Please keep in mind, that I'm not a native English speaker and I write in a different language. I did my best with the translation though.
'Good morning... Hi. I just wanted to let you know we have free sits in the first class.'
'I thought maybe you'd want one. You can sit comfortably there. And talk.'
'I paid for the seat 22C.'
'I can imagine first class is more enjoyable. If I became rich, I will always book there.'
'I don't get it.'
'I don't want anything for free. I prefer to earn it.'
Pause. The boy:
'I miss something. Can you help me?'
'I'm really thirsty. Can you bring me some water?'
Stewardess comes back with a water and wine.
'I wanted only water.'
'I'm also thirsty. Your name is Leon, isn't it?'
'Yes. And yours?'
'Caroline. Are you a model?'
'Everybody asks this question.'
'You're so beautiful... I'm sorry!'
'I'd rather be a garbage man. I despise models.'
'They are useless. They don't exist. Imagine I do modeling. I would be on a billboard downtown. What difference would it make? Mo or someone else, who's gonna even notice. Do you agree with me?'
'I don't know... I've never thought about it this way.'
'You did. Let me prove it to you. When you think of a typical model, what's the first adjective that comes to your mind? It's dull, right? That's what everybody thinks of them. Pretty, but dumb.'
Pause. The boy:
'How about you? Have you always worked as a stewardess?'
'I started at uni. Four years ago I changed the airline. I don't know any other job.'
'Are you satisfied?'
'Maybe, I don't know. I have nothing to compare it to. Sometimes I wish my life was more stable.'
'But people respect you, don't they? You are necessary. It's not another bullshit job.'
'I'm glad you admire my work.'
'I'm jealous. I could have never thought so of myself.'
'I'm sure you did plenty of good work.'
'Well I haven't. I never got a chance. They always say I'm too young and unexperienced. Bullshit. They keep me at distance out of envy.'
That's why I'm on this plane. I'm going to do something great.'
'I got to go.'
'The flight is long. Maybe you will change your mind.'
So here we learn so much. The protagonist is extremely pretty and actually annoyed with everybody pointing it out. He's a bit immature yet on a task to prove himself capable. The stewardess on the other side is attracted to him and a bit shy.
Doesn't sound like you've learnt all of that from a stranger in a five minute talk, does it? At least to me this dialogue is not satisfying even though I got a pretty valuable information.
As I want to improve my writing, but don't know which way to go I will welcome any feedback and highly appreciate any advice.
