So we are 'between houses' for 10 days or so, and my DBro and his DP have kindly said we can stay in their (small) spare room. We know this is a big favour and intend to be very respectful and helpful. They are a bit broke so for eg we did a big food shop and will keep the fridge stocked for everyone. I'm buying a couple of things they need for the house and we'll do as much housework as possible. The thing is that they are a bit scummy aBOUT a couple of things, like the state of their fridge, and never cleaning the loo. Some things are very clean so it's a bit odd. Anyway I organised the fridge when I brought the shopping in, and I just had to stick bleach down the loo
which has not been mentioned. AIBU? How can I help without seeming critical?
