you are right starbar, catwoman just had loads to do in one day - which is still flipping impressive and hard work and there were probably a few instances of multitasking like doing other stuff while the waiting for the washing to do.
it doesn't mean you have one hand on the typewriter and the other one filling in a form with a feather duster between your toes all at once - it is 'slicing and dicing' the tasks logically for convenience, and 'while your there, do that' stuff.
though you may go round the house collecting washing but dusting as you go, or maybe with the phone clamped to your shoulder.
the simplest piece of multitasking, that my ex always seemed unable to manage was making tea and toast
my way -
ask if he wants T&T,
collect used cups,
go into kitchen,
take kettle to sink,
leave cups by sink,
fill up put on to boil,
get bread in toaster,
while thats doing,
go to fridge, collect -margerine, jam, milk,
go to cupboard collect plates, knife, spoon.
go to other cupboard and get tea and sugar,
go to sink wash cups,
by this time kettle is boiled,
pour in cups, butter toast,
add milk - serve on a tray
his way
ask if i want T&T,
goes into kitchen and gets bread out of cupboard,
goes to cup cupborad, then remembers we have just used some, comes back into living room collects cup and washes them,
put them near kettle and fills with teabag and sugar,
while there picks up kettle and fills at the sink and puts it on to boil,
goes to toaster,
inserts bread then stands around while these two things do their job.
once bread pops up, goes to fridge and gets out stuff, comes to living room to ask what i want on my toast,
opens tub a and jar and then looks for a knife,
butters toast.
fills cups,
