What does the saying "don't smile till |Christmas mean?

It's an old-timey thing new teachers are told -- so they will (hopefully) get control of their classes in the fall by seeming stern and strict! The thinking is that if a teacher smiles before Christmas, he/she is a pushover. Too nice!!

Thank you.
