Most organizations don't fall apart as a result of one big blow. Most relationships don't end because of one grand argument. Most lives don't fall to pieces due to one sad event. No, I suggest to you that sustained failure happens as the consequence of small, daily acts of neglect that stack up over time to lead to a blow up – and break down.
Try to find someone with a sense of humor. That's an important thing to have because when you get into an argument, one of the best ways to diffuse it is to be funny. You don't want to hide away from a point, because some points are serious, but you'd rather have a discussion that was a discussion, rather than an argument.
