My husband will occasionally talk to me about the need not to waste energy and money. He'll snap off the kettle as soon as it boils. Switch lights off so the corridor and landing are dark. That sort of thing.
We both have expreience of being hard up and I'm quite frugal by nature - but will say to him on these occasions that I think he goes a bit far. But he'll say righteously 'It's a waste'. This is more sort of low level bickering which neither of us minds.
However because of sleeping problems we'll often end up with him going into a different bedrooms. On several occasions in the past I've bought him an early cup of tea and noticed he's had the radiator on, but the window open and each time I've said. 'You forgot to turn the radiator off when you went in last night'
This morning it happened again - radiator blasting heat out and icy cold air coming in at the window - and I said, 'I keep reminding you.'
It emerged that although we rodo this radiator off, window open routine in our joint bedroom every single night, he somehow hadn't worked out - despite my earlier promptings - that he should do this in the back bedroom he retreats to.
Would you be annoyed?
