Dialogue is perhaps the most tedious and difficult part of writing. But it’s not only necessary, it is essential to proper storytelling. After all, you’re letting the characters themselves tell the story, in their own words.
To some degree, this becomes more natural in its creation if your character has really come to life in your own mind. Then you’re harnessing that aspect of your inner workings rather than having to build your mental camp all over again every time you sit down.
This isolated aspect of your imagination continues through the day, and at the end of it often has something revelatory to say to the rest of the world, including yourself.
Writing is not a lonely occupation. (But clearly, it is an occupation — your mind is invaded by all kinds of beings!)
Then i must live in a country full of writers.
Most of the population appears upon first examination to have had their minds invaded by something.
And it isn't nanites.
For example: The blood curdling scream that has just emanated from next door.
The Xbox has just kicked his butt again.
