I believe so.
The funny part is that when DH and his sister get around their parents, they, too, get sucked into the drama. Normally, they're pretty drama-free; however, the whole family gets so caught up in trying to keep each other happy that they all stress each other out. They can't just relax and enjoy each other's company. They all have to be doing something all the time, then they fret that someone's not having a good time, even when there's no reason to think so. This, of course, leads to them NOT having a good time because they're all so worried and stressed. It's bizzare to me.
