My father is an enneagram type 7w8. At times his wing influence is so strong he could be mistyped as an 8. Ime, with type 8's and those with a strong 8 wing, there is a over-riding sense of Honor in all that they do. They are open, honest and direct in their dealings with people. You always know what is on their minds and where they stand on any given issue. Also, you never wonder where you stand in relation to them. If there is something they don't like they tell you straight air it out and then seek resolution. Since 8's have a line to type 2, they are often generous with their time and energy and have a large circle of freinds (and sometimes have difficulty saying no, especially when it comes to their own children). They aren't known to hide and make petty swipes. They are very much "what you see is what you get". They also generally aren't known to attack or bully (that's the domain of CP6's). They also tend to engage in open dialogue and encourage open discussion because they value truth and honesty. Also, if they sense any kind of underlying issue which needs to be addressed they will bring it out into the open and confront head on. Also, They aren't petty, nit-picky, or critical people.
