Good list, but vacuuming only monthly is something only a person who hasn't had hardwood/tile floors would suggest. Once you've seen how much dust and hair collects on the floor, you're not going to want to do it less than weekly.
It's laid out by room, but at least for me that's not how tasks work. I don't think "yes, I must vacuum the lounge now" or "today I must mop the bathroom". Instead it's more like "now I'm going to mop the house" or "time to vacuum". Because the hardest part of any of these chores is the initial hurdle of getting started, but once you've started it's just logical to do the whole house.
Plus, the guide would be enhanced by a place where tasks can be physically checked off, so this person can see for themselves very clearly which tasks have and have not been done in the allotted timeframe. (They would have to have a specific day of the month/week where they always rub out the ticks.)
As you say the initial hurdle is actually getting started, breaking it down into small tasks can be more encouraging. For me if I think "I need to hoover the house" chances are I'll procrastinate. If however I focus on hoovering a single room I end up 90% of the time doing the whole house.
Pretty solid list, but I would add a bedroom category. Also I feel like I wash blankets more often than every two.months, but I have a sweaty girlfriend.
I think the blankets thing might be separate from sheets? I never wash blankets unless something spills or a dog gets in the bed and leaves a mess. Why would I? There are always sheets between the blankets and my skin and I wash the sheets every two weeks.
I think that it is more about creating a routine for this particular person than the dog being neglected. Having the dog water on the list normalizes everything else. There was no instruction to clean up dog pee everywhere either.
I suppose that's another way to interpret it. The "clean up spills" part made me a bit concerned as to the type of spills and conditions in which the animal would be living.
Just because you don't remember being told common sense facts, doesn't mean you weren't. It probably happened at some random time without you making much of it, you just incorporated it seamlessly into your worldview. Now you look down on others for needing the same support you did when you were a child.
