Is your life out of control?

I'm not really sure how to interpret this message my dad left for me:

I left my lunchbox on the dining room table in my parents house. When I went to put it away, there's a book on tape called "Boundraries: When to say YES, When to say NO, To take control of your life" and a portable mace key chain.

So I guess my parents think I'm letting people take advantage of me and I have trouble setting boundaries and I feel guilty if I do. My parents are usually right about things. Crap.

Or it's coincidence and my dad just left it on top of my lunchbox by accident. Totally possible as well, haha!
