My sustenance 

We've got one kid, Raul (AKA Gabriel. As in, namesake of the Gabriel House. Their first kid, I believe), who is severely autistic with some other health and mental problems. This morning I realized I had never seen him smile. It made me sad, and confused, and I told God I didn't get it. I didn't know if he even COULD smile.
But God decided to show me a little something. While walking with him this afternoon, not only did I see him SMILE, but I saw him LAUGH.

Sustained by the little-big things.
