Oh likes to point out where I'm wasting time which annoys the fuck out of me
Who's right here tho.
You're doing the ironing, you iron each item and put into a pile then after you've done all of it you seperate into piles for the (6) people it belongs to.
Or
You iron each item and put it straight into a pile for each person.
This seems obvious to me 
Yes I realise it's a bit pointless but I want to show him how wrong he is
