history: Someone told me something at work that was inappropriate of them. I went behind them and told the manager what was said as I was concerned . Turns out the person was lying about even doing it and was fired for it. So I accidentally got someone fired for something at work.
current: That sounds bad. I know it wasn't intentional but what happened? 
next: The person bragged about doing something, 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.
