total toast

I lied my way through my physics tutoring session today, nodding about notations, giving muffled mmm hmms when he asked, So you understand how we got that answer, right? It took an hour to do one problem--a cruel reality regarding the subject that I'll never get used to, even with a genius for a tutor. The thing about having a genius for a tutor: he can also tell when I'm lying, but he doesn't just come out and say it. He'll smile and say, OK. You tell me how we got that answer. Which usually means I'm toast. Like today, I was total toast.
