history: When someone at work ruined our project and wasted my time it made me incredibly angry. I don't understand people who are just miserable and like to ruin things on purpose. I had someone at work ruined our project and wasted my time it made me incredibly angry. How'd they ruin it? Sorry *ruin. They simply decided they would not do the project according to instructions and just wanted to give me a hard time and ruin the time we had to work on it.
current: Sounds like a mess, were they punished in some way? 
next: I hope so. I reported them but who knows? You know how some bosses don't care :/
