I could have written that post. We actually plan to have leftovers so that some nights we only have to reheat our dinner. We don't usually have leftovers from a meal on Monday until Wednesday.
In our house, the one, who cooks or grills does not clean up nor load the dishwasher.
The cook for that meal makes sure that the good left overs are put into the plastic containers or zip lock bags and put into the fridge or freezer.
