Well, Mrs Evans, I’ve done my best to look after David. I’ve tidied his room up every day, got him a meal together whenever he needed one and made sure he’s always had a clean shirt to put on. It’s not been easy, with two of my own to worry about, as well. David had the best of attention, I must say. But now because I asked him to give up bringing that American friend to his home he has got quite and unfriendly. He comes in at all hours and his behaviour—well, it’s quite hard to put up with—and it’s all because of this friend. I’m sure he’s a bad influence. You see, David is a visitor and doesn’t fully understand our ways.

He used to study most evenings. He’s got through quite a bit of work. He did up his room quite nicely, with bookshelves and large posters. He’d ask Mr Smith and me up for a drink and cheer us up with songs from his country. He’s very good at the guitar, you know.

I don’t want to appear as if I’m running after him, but it’s about time we made it up. I’m sure he’s upset because I blame him for that. It might be a good idea to take him out for a meal, perhaps even with his friend. I don’t know whether it will do any good but we can try. I’m glad I’ve had this little chat with you, Mrs Evans, and I’ll let you know how I get on.
