I am an anti-faffer. I think going everywhere by train and bus as a child helped. I may procrastinate but that doesn't affect other people.
MrNC is a faffmeister extraordinaire.
After 20 years I've got him down to bearable levels. The most annoying thing he does now is claim to be "all ready to go" smugly when I'm still getting dressed. I've learnt to respond "No you aren't" as invariably he claims to be ready, he "just" needs to put his shoes on, go to the loo, get a drink for each child, find a tool, make a sandwich...
He is dyslexic and his parents are 10x worse. These are the people who kindly offered to drive to my workplace where I had bought a futon, and drive it and me to my new flat. They arrived 2 hours late (MrNC had warned of this), but it hadn't occured to them to empty the estate car first of the tool box, picnic chairs, hamper, and so much junk that the futon couldn't go in. So we spent the next two hours using the tools to dismantle the thing so it could fit on top of it all.
Once in, I left and got the tube. They arrived three hours later (about an hour drive). There would have been at least an hour of debate about which way to go. They also used to regularly miss flights but now drive to France as ferries are much more understanding. At least they are lovely people and very nice apart from the faffing!
MrNC can do a few one-pan tasty meals, and now has a dyslexic-friendly cookbook that spells out Find these ingredients, a saucepan with lid, and a pan. Put kettle on to boil. Turn on hob. Put x in saucepan, on hob, and add boiling water. Now chop y and z while x cooks, until they look like this picture. It's great!
