The person with bipolar disorder will have manic episodes without any need for a trigger. There doesn't need to be a call from someone saying, hey, let's go on a vacation together, or there's something coming up this Friday that's really exciting, or let's enter a relationship together of one form or another. The person with bipolar disorder will have episodes of mania or episodes of major depression without any need for an external stimulus or environmental trigger.
