What's a family without some sort of drama?
When dad was alive, he used to refer to his better half's parents home as the "Funny Farm." We'd all have to go sooner or later. Have a meal. They'd drink some wine. Then if someone was silly enough to bring up Politics, the **** would hit the fan.
For as long as I can remember we've been "taxed to death." I heard it all the time. Of course, no one disagrees.
However, when a long-standing family dynamic changes; i.e. one person crosses the floor and over the comfort boundaries to bonk another said family member, well I'd have to say that the fire of the dragon has come alive.
You can assume you know your family. For better or for worse. But when the truth comes to light and that certain individual won't communicate honestly, while all around those who watch, hear and feel know reality... a drama unfolds. Which begs the question, if you can't trust your family, then who can you trust?
