The writing I did today was complex.
The character was in a 'learning' situation. I fought to stay true to the message though and not go off on a tangent - telling about the mechanics of the situation instead of dwelling on the heart of what was being learned.
Specificaly, the hero/heroine is in 'squire school' and the 1st few days of testing. I got caught up in what each test was, how he did, and his interactions with his peers.
I finally had to pull back and say, 'Listen. This is not about what an heraldric banner looks like, what each symbol and charge means, but the stress the character undergoes trying to remember the dozen or so banners of the knights of the realm, and the relief/disappointment at the end of the tests. I'm not writing a 'Tolhoffer Medieval Combat' manual.
I know I'm not the only author that this happens, too. I'm glad I recognized it. I hope I continue to recognize it.
