I'm going to refuse to clean the bathroom in our house.
Is there a reason behind not cleaning your bathroom?
I just can't stand seeing all kinds of dirt everyday and I'm the only one that does anything about it.
I'm sorry you are stuck in this situation. It's expected that people maintain a clean home, but it doesn't abdicate your duty to clean up.
I'm going to boycott cleaning until they get the message.
Being passive aggressive about your roommate's cleaning of the bathroom and refusing to clean is a bad idea as there is still no excuse for not cleaning. You have a responsibility to the household here. Talk with your roommates about the situation instead of trying to use force.
