It was so much worse than I feared. Not only was the house incredibly untidy, the whole top floor now served as a makeshift brothel.

I hurried upstairs to collect my e-reader, unaware of the new purpose of my bedroom.  On seeing the crush of naked bodies dotted in pairs and threes across the room, I rushed in and out as fast as possible to grab my belongings from the top of my chest of drawers. Then – in a rather shocked state – I headed straight back downstairs again to have words with my sister.

She really did need to start cleaning up the place.
