i live in London, its not ideal sharing but, its what I do and there's no escaping that. Both perfectly nice flatmates, one works funny hours and spends all his time off at the gym the other is a 9-5 person. I work 3-4 12 hour shifts a week, sometimes days, sometimes nights. Im not the biggest fan of spending my days off cleaning so, we have a cleaner. Ive lived here along time and Ive known her for years. She's not the best but she does the jobs we dont do. And, thats it really. When the rent went up they both said they were no longer willing to pay for the cleaner, I told them that in that case I would pay for her but they needed to clean up in between. That has not happened. They arent filthy, their bedrooms are immaculate but, for instance, she comes in the morning and the kitchen bin is practically overflowing I only emptied it two days ago because they know she is coming in the morning. I just put one of them loo blocks in and under the rim is full of yellow pee, neither of them go near it. Of course she will tomorrow.
When I tackled them they said I used the living room more than anyone I do and the one that also does shifts said he eats at work and doesnt cook so why should he clean the kitchen. Thats not your chicken in the oven right now, then?
