Amongst many other things more serious than this, DH insists on ripping off the plastic tops attached to bottles to allow for better recycling. At first I gave him the benefit of the doubt, maybe he wasn't aware of what the new design was about. But every time he takes the tops off it leaves behind two very sharp plastic spikes which stick in your hand every time you use the bottle, so eventually I asked him not to do this. He said ok, as if he had now realised what this is for, and I was relieved that for once he'd actually listened and was taking my advice. But ever since then he has ploughed on ripping every top off as before. Is he doing this on purpose? It is driving me mad. For context, it takes a lot for me to pull him up on things, and I know for a fact every time I speak up he will confuse the hell out of me with mad counter-arguments, so much so that it's easier never to say anything. And as this example illustrates, I am wasting my breath saying anything anyway.
