My own mother’s Stern Look is so effective that it was named “The Clare Stare”, and is feared and respected by children/teens/errant business-people alike.
I tried out my own Stern Look today, and thought I had aced it as my 2.5 year old very suddenly stopped the over-tired grizzle-fest that was approaching fever pitch…but then she put a concerned hand on my arm and said “Mummy!? Are you alright? Why are you making that face? Do you need to do a poo?”
It would seem my Stern Look needs work.
