It’s hard, but sometimes someone has to be the grown-up. Such as when a young girl (6 or 8 years?) at the grocery store points to me and whispers “Look at her!” and giggles with her similar-age companion.
I met her eye and replied, “Yes, I’m wearing Sounders green* today for the game. Do you like the Sounders?”
Eyes like saucers, she just stared at me with deer-in-the-headlights, “OMG the grown-up heard me talking about her” shock. I smiled and walked on.
