What Was I Thinking?

Guitar lesson last night was a dismal. After a hiatus of 2 weeks my left fingerings were clunky and right-hand plucking was such a beginner's grade affair. To make it worse I clipped the right-hand fingernails. You're supposed to maintain some nails. What was I thinking when I clipped them?

Needless to say the instructor was not amused and he kept on harping how slow we were to sight-read the music and respond correctly. And I being a smart-ass and the only working adult in the class tried to be apologectic by admitting my sub-par performance, all in jest, of course, and how the holidays had kept me busy. Busy? Lol. Busy not-practising, that is.
