Meanwhile, I haven't figured out how to fix the light in the lounge (problem described here). I'll take the broken fitting to B&Q tomorrow, in case they can sell me something suitable, but otherwise I think I'll have to swallow my pride and get an electrician to come out.
In other news, I had my penultimate Japanese class of term this morning. We have a test next week, so I'll need to do a bit of studying for that, otherwise I can't progress to next term (I'd have to retake this term). Anyway, the class went well, although I did seem to wind up playing "straight man" for the sensei's teaching approach, when we were learning about times of day. E.g.
Sensei: "This is how you say 1 o'clock, 2 o'clock, 3 o'clock, so how would you say 4 o'clock?"
Me: "..."
Sensei: "Yes, that would be logical, but no!"
...
Sensei: "So, how about 9 o'clock?"
(There are two ways to say "nine" - "kyu" and "ku".)
Me: "kyu ...?"
Sensei: "I was hoping someone would say that. No, it's 'ku ...' "
D'oh! Ah well, it's all informative.
Anyway, now to decamp to a fume-free room.
