I have to work with a dentist who is a dirty man every Wednesday 
I think he is immature as an adult.
And he can’t communicate with patients well .
He always talks to me.
He doesn’t explain to patients about treatments.
I’m always irritated 
Today, I got along with him until middle of work.
But he kept his hands off his smartphone although he finished his work.
So I warned him “ Go home if you don’t have any work.”
He was surprised.
And he rushed home
