person A: So_comma_ I accidentally threw out my co-worker's lunch today at work.
person B: That happens sometimes.  Was it mistaken for something that might have been sitting there forever?
person A: Yeah_comma_ it was when I was gathering up my trash when I was wrapping up my lunch_comma_ so it was an honest mistake. I felt pretty awful about it.
person B: I'm sure if you explain it to them_comma_ and maybe treat them to lunch another day_comma_ they'll forgive you_comma_ if they haven't already.
