When I was in those situations, I usually left the house and walked somewhere. But my mother also didn't care that I was gone. My whole point in leaving was trying to get her attention, and for her to worry about where I went, but it NEVER happened. It's kind of sad, but also frustraiting that I never got my way. ~ ~
I'd offer you a ride as far as I'm going, which is about half an hour or so away from Salem, but your parents would have to pick you up from Newberg, or Donald, which is right off of I-5.
