My reasons for having not posted new chapters.
My muse seems to have abandoned me.
I lack motivation.
I'm too busy to write.
I'm too bored to write.
I can't think of anything to write.
I don't like what I wrote.
I have a headache.
I've been sick.
The weather has been too nice.
It's too hot.
Worthless excuses, every one of them.
