I'm talking about tense, as in past, present, future, etc.
My novel is written in the present tense, but I find myself slipping into past tense every once in a while - and I'm not sure why! And my internal editor gets all "Hey, crazy lady, you're doing it again. Now go back and change all of that past tense crap you just wrote." And my disciplined I-will-finish-this-novel-if-it's-the-last-thing-I-do writer self gets puffed up and is all, "Hey, internal editor...SUCK IT!"
Does this happen to you? When you catch it, do you fix it? Or do you trudge on and fix it during the revision process? I already know what some of you (I'm looking at you, Katie Ganshert! ;p) would do, but feel free to chime in anyway!
