When you charged them again
You'll do it again. A message will go unanswered, and by Thursday you'll have decided what it meant, and you'll have spent an evening there before you remember there was a method. Or you'll say the thing in the meeting, "you clearly don't want my input", out loud, and watch it land, and know as it lands that it was a charge. This chapter is for afterwards.
The first thing to know is that one charge isn't the habit back. The habit was believing every charge on arrival. What's happened is that you believed one, late, and noticed. Noticing is the change. The version of you from two months ago wouldn't have noticed at all, and would be on the third day by now.
The second thing is to do the three causes late. They still work after the charge has set. They work more slowly, because you've had an evening to build the case, but the case was built on one sentence, and three more sentences will loosen it. Then ask yourself whether the slip matters enough for the plain question. If it does, ask it, tomorrow, as though the evening hadn't happened. If it doesn't, drop it, out loud if you need to, "I've decided that was a Tuesday", and let it go.
If you said the charge out loud, repair it. Not with an apology for everything, but with one sentence about the act. "I said you didn't want my input, that was unfair, I was annoyed about being cut off." That's an objection to the act, correctly aimed, arriving late, and most people will take it, because most people have said the same kind of thing themselves.
Then ask which belief let the charge through. Usually it's one of the chapters. "I'd never do that" on a day when you'd done exactly that. "It's a pattern" with two instances and no varied situation. "The tone was obvious" from an email read in a cold voice. Find the belief, reread the chapter, and carry on. Don't count clean days. The aim was never to stop charging. It was to stop being run by it, and one charge you noticed is evidence that you aren't.
