i can empathise with this. I'm also a slightly ocd neat freak (can't sit down and relax till i've cleared my peripheral vision of aesthetically displeasing clutter) and i live with my borderline feral girlfriend. I have come home to find knickers on the kitchen surfaces, week old washing-up festering and there is nearly always a pile of shoes in the toilet where she kicks them off then leaves them. I'm in near permanent state of nervous breakdown about it. Anyway, i better leave it there or i may rant properly. I bore myself going on about it to her and and anyone who'll listen...
oof!
