person A: I accidentally left a very important document at my house that I needed at work. It made me look foolish in front of my boss when I didn't have it :(
person B: Oh no. Did you explain it to him?
person A: I did. He laughed it off_comma_ but it makes people believe you aren't up to the task. So_comma_ it's not a good thing
person B: You'll be more careful next time. Everyone makes mistakes.
