How about I never wash my hands?
That's sounds dirty literally. Why wouldn't you wash your hands?
I don't have any reason, I just don't want to.
Although you are free to do what you want, that doesn't mean you always should. It is much more sanitary and healthy to wash your hands. Plus, you could expose other people to nasty germs by touching things after you don't wash.
That is too much work. Washing my hands is a stupid idea. I'd prefer doing my own thing than following such stupid rules.
What if other people were like you and started touching you and your things with dirty hands? You probably wouldn't like it either, so I think you should at least consider keeping people healthy by maintaining good hygiene. I know you used to be one of the cleanest people I know, and I have always admired you for that.
