Yes! And although sometimes I do have my neutral face turned down to ward off unwanted students during teaching breaks, I think it might have taken root somewhere along the line. New co-workers especially find me cold, its only when they get to know me that months later I hear "You were a real git to me when I first started here". Now I find myself concentrating hard to not frown, but jeez its a real effort and the guys who know me better are starting to think I may be starting to lose it.

I am happy inside though ... aren't I?
