So you should. And the fact you do says a lot about you. That's the great thing about us non-fats. We actually take personal responsibility for things. We feel bad for not giving 100% all the time. We don't just wallow about, whinging about how we are oppressed and how nothing is our fault. Hell, I did my fair share of skiving at college, and some days at the gym I'll skip a set or two of squats. I feel bad for it. Then I feel good for feeling bad. It reassures me that I will never be a ham.
