I don't wanna go to class or even meet my students in the corridor...

...because the little monsters keep making me smile. Something funny (bad funny) happened to the nerve that goes to my upper left teeth last week and now it hurts to expose them to anything slightly chilly - even classroom air. But! this has made me realise just how smiley my students make me. Even when I am trying to be grumpy-not-showing-teeth-lady.
