A “non tidy person” might come in from wherever, be pretty tired, have an armful of stuff from their car, and have their kids demanding things from them (whether or not they repeat, exasperated, to please give them a minute to get in the door.) They might drop the armful of stuff on their habitual dumping spot (for me, it’s a metal table in the entryway to the kitchen, or for keys/mail/headphones/wallets, it’s the “mail place, a counter near the metal table.) They then kick off their shoes (which may or may not make it into the shoe rack/closet) and take off their coat, and then turn to helping/commanding their DC to take off their shoes and coats (hopefully before they drag dirt into the house and empty their pockets. Who knows where the DC have placed their backpacks/lunchboxes/whatever else they carried in with them.) Now they’ve got an armful of coats, kids still asking for things, maybe they notice the dog had an accident in the house or chewed something up during the day, everything is stressful and chaotic. So they put the coats down on the back of the couch, go and fix a snack and some drinks for the DC, clean up after the dog, what have you, and then…
Oh, they better get dinner started because it’s getting late and DP will be home soon and the kids still need to get their baths and get to bed at a reasonable time because if they don’t, they’ll be huge PITAs tomorrow. So they hurry up and get dinner on the stove and/or in the oven, making a normal amount of cooking mess, and then head into the bathroom to run the bath for one child, then come back to the kitchen to start cleaning up. Maybe they get a little bit done, like the ingredients put away, but none of the dishes are attended to yet and the countertops are dirty. Maybe the DC start fighting or asking for help with their homework or one wants their attention, so cleaning is on hold until that’s dealt with. Now the bath is full and it’s time to help one child into it. They sit with them for a few minutes and get them clean and dry and into their pajamas, and then DP is home and dinner is ready to be taken out and served up.
Everyone sits down to eat, then carries their dishes to the sink. DP takes over bathtime for the other DC, while they work on cleaning the kitchen and doing dishes, and then they go to help with bedtime. After all the kids are asleep, they survey their home, and while the kitchen is clean and tidy now…
There’s the coats on the chair, shoes outside of the closet, the stuff from the car in the dumping spot, the unopened/unsorted mail, the DC’s backpacks/lunchboxes/pocket contents and all of the things they were playing with, there’s decorative couch cushions on the floor, snack dishes and associated crumbs, clothing that didn’t make it into the laundry hamper (which is full, btw— better get a load started), bath toys in the tub and towels not hung up… It’s a whole disaster.
Then they’ve got to choose: do they stay up for another 30-45 minutes taking care of all of it (aka, the “evening reset?”) Do they take that time to sit with DP, or maybe take them to bed and fool around? Maybe they desperately need some decompression time so they opt for a nice long shower themselves (or maybe not, because all the hot water is probably gone and also they’ll need to fold the laundry once it comes out of the dryer. Also, the dog needs his evening meds.)
If they don’t choose to clean everything that night, then it gets left for tomorrow, and the day is started with a less-than-tidy home. For a lot of people, this is the start of cumulative mess that they’ll fight and fight and be overwhelmed by, and then it might become difficult to get started.
But what’s also difficult is, in those chaotic moments when you’re getting in the door and trying to take care of all your dependents and responsibilities, is to put all the shoes in the closets, hang all the coats, get all the backpacks/lunchboxes properly emptied and put away, the mail sorted, the stuff from your car taken care of, the dishes done and counters wiped while you’re cooking, etc.— aka, “cleaning as you go.” (Also, getting your DC and DP to clean as they go as well.)
So then it becomes a matter of personal preference and circumstance: 1) Are you able to tend to those things immediately, or are you forced to do them when you get a chance? And 2) Would you prefer to do it now, or do it later? After all, it takes the exact same amount of time to put something away whether it’s done on your arrival home or after the DC have gone to sleep; it’s just a matter of whether you actually do it…
A cleaner, tidier home simply requires that one does more work to make it that way, and for it to be done with greater frequency if one wants a home that is constantly ready for unexpected guests at any time. And as I said… it just feels like habit to “tidy people,” so they don’t see it as much work at all.
