I'm planning to clean the bathroom with my roommate's toothbrush.
That is gross so you should tell him so he won't use it on his teeth.
I didn't think about that, I see your point.
It's disgusting and disrespectful to use something so personal of theirs to clean something so dirty. There are better brushes out there to do the job, why did you have to pick his? Why not use your own toothbrush then?
You are so biased against me. Don't tell me what to do I can do whatever I want.
Would you feel the same way if he scrubbed the toilet with yours? You should respect his property and only use tools you buy for cleaning.
