Social interaction is a key part of the game. You will have to do a lot of talking, be it to your fellow Heroes or to the person you're about to punch.

Most social interaction is considered automatic actions, meaning that when you type it in, your character gets to say it. There are a few cases of where it might be a dice action though. These usually happen when you are trying to convince someone or something to see your point of view or to not do an action, like hit you. These would be considered dice action, and would follow the standard rules for dice actions.
