I was so mad at my husband I used his toothbrush to clean the toilet.
Oh wow, that's terrible. What made you so angry?
We had an argument and he wouldn't listen to me at all. He never respects my opinion.
You shouldn't use his toothbrush to clean the toilet behind his back. Is this some kind of payback you are doing because it's very unhygienic and disrespectful to the person. You will end up living with a guilty conscience.
He deserves it, he was really terrible to me.
Using his toothbrush to clean the toilet is not very nice. Even though you're upset with the way he treated you, you should not get even with him. You should tell your husband how you feel and try to work past your feelings of anger.
