Oh, was that a mistake...
My wife complained yesterday that she had been cold at work and couldn't warm up when she got home. So, being nice, I went and turned the gas wall heater up in the bathroom about 5 minutes before she was due in tonight, knowing that she usually goes straight up for a shower.
Not tonight, she decided she needed to prep some food for tomorrow first, so spent 15 minutes in the kitchen with chicken and veg. Then she was messing about in the bedroom, changing the alarm clocks so they would be the right time in the morning. She got stuck with mine, it wouldn't change. That's because mine's automatic and will update itself when the time comes.
Eventually, a good half hour more than normal behind schedule, she headed for the bathroom, talking as she went, so I followed her. Whoosh - the hot air hit me like a ton of bricks, I couldn't breath! She was saying how nice it was and I'm unable to speak.
I had to come out and wave to say I'd talk to her when she's finished. 10 minutes later and I'm breathing again, after a couple of puffs of salbutamol, but have a heck of a sore throat now. A bit like when you've been dry coughing non-stop for 15 minutes, that sort.
Had I gone up and turned the heater back down when I realised she wasn't going straight in then maybe it would not have been bad, but it was like a taste of the sahara. I may be nice and turn the heat up a bit for her, but I'll not be wandering in when it's like that from a cold landing/hallway again.
