Have you and your brother given any more thought to renting out that spare room of yours? There is one minor detail I forgot to mention - I have a dog. But he's only a little dog! His name is Watson and he's a corgi. Here's a picture of him:
That's actually from when he was a puppy because I can get any recent pictures of him because they're in my old flat and I refuse to go back there but he's not much bigger, I promise. He won't make any trouble. I'll pay extra. Name your price. I have to get out I am dying here.
