These people don't usually speak up first and don't speak without a great deal of consideration. On one end of the scale you see people who are so direct, they're almost blunt. To make a point, they'd say exactly what's in their mind. They let you know where they stand on an issue, speak right up and are not at all reluctant to take a position. On the opposite side of the scale are the indirect people.
Indirect people are the kind who are a little more tactful.
They are more cautious, waiting to see what develops before acting, or waiting to see where things are headed before becoming involved. They want to see how it goes first. Instead of appearing active they appear passive. Think about yourself in those two respects, openness and directness. Depending on the situation, sometimes you might be more open and sometimes you might be more self-contained.
