It's really amazing that you have these fond memories of your students
Haha, those pictures of people smiling on the job, reminds me of ads of putting smiling while jogging. I have NEVER seen a jogger without a constipated expression on their face let alone a smile
I know man. Those stock photos kill me. I love the ones of a room full of smiling students. So real. Happens every day!
But... what about after the jogger has crapped in his diaper during a marathon? Perhaps then we'd see an expression of relief.
