Joelle had such an occasion just a few minutes ago.
She came up to me with a h-u-g-e grin on her face, her eyes lit up like Christmas lights.
"Mom! Mom!" she exclaimed with a very high excitement level. "Do you know how to spell DVD?...It's D...(pause)...V...(pause)"... (wait for it)... "D!" Wow, did she ever look triumphant!
I was giggling on the inside, but on the outside I was very proud of her for figuring that out. All by herself!
