My Secret Snack Time...

I recently started sneaking snacks during class whenever I can get away with it. I usually grab a chocolate bar or some chips from my desk drawer when the students are distracted by group work. It feels so naughty and rebellious, but also comforting like a guilty pleasure treat. Of course, I'd never do this if I didn't feel confident I wouldn't be caught... Is everyone else having snack breaks too? Am I totally nuts for doing this or is it normal to crave some extra energy midday?
