Crap

Me: A paper has already been written about that. 
Him: Do you mean this (while glancing at the paper)? This is crap. Who wrote this? 
Me: I did (while looking at him straight in the eye). 
Him: I’m sorry. This is so awkward (his face reddening in shame). 
Me: It’s fine. I’m professional enough not to take offense at your remark. You obviously have not read the paper so… (shrugged) 
Him: I browsed it. I’m so sorry. This is so awkward. 
Me: So what makes it crap? 
Him: (bowed his head and said nothing) 
Him: (after a long and uncomfortable silence) I really want to apologize. It was unprofessional of me to say that. 
Me: Forget about it. It’s nothing, really. I know myself too well to let such things bother me. So it's crap. You can throw it away. You don't have to use it. Let's just move on, okay? 
Him: I’m new here and what I did was unethical. 
Me: Then learn from it.
