I ran away once. I was about 8 at the time and I packed an old, navy, hard back suitcase I had. Perfectly sized for a runaway. I made it as far as the far edge of our front yard and I sat there for about 45 minutes (which = 6 hours in 8 year old time). I don't remember what pissed me off so badly that I needed to escape, but I was irate that I didn't have it in me to stay away. That, and that no one came to get me (although I'm sure my mom kept a watchful eye on me out the window - like I said, I didn't go very far.
I didn't leave a note, but if I did I wish this is what I wrote. My favorite part..."Be sure to say good bye forever." The P.S. is a close second. I love how she's so prepared.
