You can scrape burnt toast, but you can’t unburn it. Some mistakes you just learn from and make a new slice.

There is a difference between repairing something and starting again, and some mistakes only allow the second. Scraping gets you a worse version of what you wanted and costs you the morning, and at some point the honest move is to accept the loss, change the setting and put new bread in. Not everything is salvageable, which is not a tragedy when the cost is one slice.

Where something went wrong this week, ask whether it can be fixed or only redone. If it is the second, say so without a long argument. Then change the one thing that caused the burn.
