Gabriel has a "vrais" twinkle in his eye when he is happy as anything

Gabriel is the most generous person in this household. Everyone knows this, and we have all learned from him.

There's another thing. When he is happy, he is beautifully happy. It's beautiful to look at, to see, I mean.

There's the expression "twinkle in the eye". With Gabriel, you can see this expression has a referent in reality, and is not just an expression.

Here, he was delighted to have a music player of his own, with headphones, just like his older brother. We were laughing like crazy, as Gabriel seeks out — and plays — Aerosmith, which is a hard rock band. He was beside himself with happiness. And his eyes twinkled all the while.
