What about people who can't multi-task?
Before I leave a room I will always look around if anything needs to go somewhere else, maybe empty cups for the kitchen, a book for the study, washing to go in the laundry bin etc. So while I am on my way somewhere else in the house I tidy and organise as I go. I don't have to think about it, I just do it.
My daughter will for example get up to make a new cup of tea in the kitchen, but will leave say a banana skin or sweet rappers on the table while she is actually going in the direction of the bin.
She probably knows I will do it next time I pass the table.
