Have you mopped many times before, or is it your first time learning?
If you've done this many times before, then you're technically both at fault.
Him for misspeaking, but you for also not be able to reason out that certain tools will work better for mopping than others. There comes a point where you need to be able to be more useful than adding more work.
Is this the only issue you have with him or are there many more things? If there are many more things, maybe we should be presented to more examples to assess a more fair opinion for both of you.
Many times and many different products, to try and clean, but only a residual comes up and due to hubby being a gardener and allowing our dog and cat to go into the bathroom, more stains are there and they are ones I cannot mop up.
Oh my, many years worth of issues lol mostly that I do not do a good job of keeping the house clean, but I become stronger and able to reason it out a lot more, so he has given up mostly, critizing and especially, when I point out how untidy he is!
Not sure how I am also at fault and especially, when he did not mean the floor, but the toilet itself.
