DH is completely impractical around the house - no idea how anything works/spatial awareness etc.
Mostly I don't care, but his tap behaviour drives me insane. Before a drink of water from cold tap, he insists on running it out for about 45 seconds to a minute.
Doesn't care about the potential water bill impact, or the environmental impact.
He says its to get 'cold' water. We have a 2-way tap in kitchen (like most uk houses).
And even if he has done the running tap, if someone switches it round to warm for anything, and he wants another drink - he runs it again for 45 seconds. He doesn't understand about the valve just by the tap head that switches it from cold to hot there. He thinks about 10 metres of pipe will all be full of hot water.
How can I help explain this bullshit to him????
