I broke one tonight. My point didn't score, and I was sure I'd jammed it into my opponent more than firmly enough (we were both using power), and it turned out I was only holding half of it. I'm going to have to remedy this real soon, since I'm running out.
I'm also a bit more cheerful because I talked with a friend about what I really want from some aspects of life, and the answer was that I'm not being unreasonable and shouldn't worry about it so much. :-)
