I can't remember the last time I showered
Why haven't you showered recently?
Because I'm lazy and I feel my parents are controlling me.
It is hard to find the motivation to do things sometimes but it is not good not to clean yourself. It could affect your health not to maintain good hygiene.
No one is forcing me to shower and I'm good to go with the way I am. My doctor said that being dirty is good for people.
I doubt a real doctor would claim that. You could get scabies if you lived in a dumpster or kept being dirty. Showering is good for your physical and mental health.
