Might be a bit euggh for some but here goes.
We have a very old bathroom and an ancient toilet that guzzles water every time we flush. It must use gallons. I've got a water saver in the cistern. To save water, and the reduce bills we tend not to flush for a wee. We have two children and I'm a childminder so there is a lot of flushing going on in our house.
Recently, I heard DP use the bathroom, flush before he used it, then again. I said, why are you flushing twice? He shrugged. I said, please don't flush twice, it is just wasteful. He has ignored me and continues to flush twice. I've concluded that he thinks his wee and poo are too precious not to land in a nice clean cistern, hence the double flush.
I just think he's wasteful arse. AIBU?
