In that case, my quirky one (one of my students) is a true friend. As I was reading The Tale of Despereaux to my class, he chimes in with, "You've got something in your teeth." He motioned to his mouth.
I scraped my teeth and grinned.
"Nope. There's still some there."
I scraped again and grinned.
"Yep, all good now."
The para that works in my room that had been listening to the book hadn't even noticed.
Thinking back, I wondered how long it had been in my teeth and why no one had said anything before. I guess I know who my true friends are!
