My husband doesn't like to smile, so he showed his joy with a "Yay!" pennant.
As someone who spends her whole day writing more than speaking, I can appreciate this! Imagine I'm holding a tiny banner that says "CONGRATS."
I also subscribe to the philosophy that if you don't know what to wear to an occasion, just wear EVERYTHING. Can't go wrong!
