Evan's team had just launched their new app. They held a big party that night for the whole staff. It was in a nightclub with an open bar. Evan began the night mingling and avoided alcohol. But, after seeing everyone else was enjoying themselves, he decided to catch up with the rest of his drinking colleagues. As he spoke to his co-workers, his speech was a little slurred and he expressed disappointment with some of his bosses. He felt it was alright to let off a little steam with his team. After all, it was a celebration. How would you describe Evan's behavior at the party: 

vulgar 

Appropriate for a work party 

inappropriate 

none of the above
