I'd agree about shared occupancy. My son has just endured 3 years of having to share a kitchen at University. He said it was like living with savages. And these are people he "chose" to live with in the 2nd and 3rd years, so people he actually liked and was friendly with. The only way he survived it was having his own en-suite bathroom, and having a small fridge, kettle and toaster in his room so he could avoid the kitchen as much as possible. He liked the people, would go out socialising and for day trips with them, but just couldn't do with the shared kitchen due to the mess, filthy cooker & microwave, piles of dirty dishes filling the sink and worktops, mouldy food in the fridge, etc. Not to mention his flatmates stealing his stuff, i.e. bread, milk, etc leaving him short when he wanted it! These were people he was friendly with!
He's just got a job in a different city where flats are ridiculously expensive and hard to get, so we'd suggested a flat/room in a shared house (which are also expensive and hard to find, but slightly easier/cheaper). He was adamant he wasn't going to risk it and so is paying through the nose, using his savings, to pay a stupid high amount for the only flat he even managed to secure a viewing for, out of town, not a good location, but to him, not having to share a kitchen (and especially not a bathroom) is essential.
He's not ND, doesn't have ADHD, nor OCD, or anything else like that, perfectly normal, and never thought he'd have a problem with sharing a kitchen, but it's been a nightmare for him. He naively thought other people would be even slightly civilised, but apparently not!
