My dad decides things in his head and nothing will change them, things he has decided include:
I have a second (full English breakfast) every day at work.
Once a week our canteen used to do a cooked breakfast of five items for £1. When that was the case I used to get two sausages, beans, a fried egg and a hash brown. They stopped doing that about six months after I started at my job, put the price up and I wasn't interested any more. I was at that job for five years and he still maintained I had a full english breakfast every day.
All of my worldly belongings are still in his (and mum's) house.
I have left a pair of pjs and some spare underwear in a drawer in my old room in case I ever have to spend the night which happens maybe once a year other than xmas. On the windowsill there is a jigsaw and money box which while technically mine are basically nostalgia for my mum and having them there keeps it as "my" room so they never got moved out. There is a box of university work in the garage. That's pretty much it. Everything else moved out with me five years ago when I left home.
My brother left home six years ago and his bedroom still has all his books, CDs and general knicknacks on display as well as underneath the bed and the garage being chock full of his things.
I asked my dad if we could put some boxes in the garage while we had carpets fitted and was subjected to a lecture on how I better take them back and not just leave them there He hasn't found the extra tiles I hid in the garage after we had our kitchen and bathroom renovated
