Need to get out of my comfort zone

Every once in a way, my dialysis tech sends his brother instead of coming himself. His brother is a dialysis tech at the same unit as him.

The problem is his brother thinks with his dick instead of his brains. And he does not know English. And I speak horrible Telugu. So, all communication between us is in a mix of broken Telugu and sign language.

Whenever an alarm goes off on the machine, he arbitrarily presses buttons without thinking what he should be pressing.

It is now abundantly clear that I need to be in control. I was getting there but took a back seat when the infection started. Yesterday, when his brother came, I was unnerved. So, I am going to get back to doing everything myself immediately.
