person A: So I accidentally got someone fired for something at work.
person B: That sounds bad. I know it wasn't intentional but what happened? 
person A: The person bragged about doing something_comma_ that they didn't actually do. Which was highly inappropriate for the job we had. I had to tell the manager due to liability issues. All for it to not even be true.
person B: Well you did what you were supposed to do. It's their fault for saying what they said. 
person A: I agree_comma_ but still feels bad to get someone fired at times.
