Everyone, really everyone, has lived in a house or flat that wasn’t as clean as they would’ve liked it.
Magnetic Spacemen are actually living in somewhere like that right now and they’re going to tell us all about it : “We should clean the house before the rats come to live in / and I can even make a sandwich in the kitchen …”
There is an answer to difficulties such as these (Dettol, soap etc) but Magnetic Spacemen aren’t being entirely serious and I’m sure their open plan dining room is at least as clean as my own. They’re from the Netherlands.
