They love each other, these two. When Ellie's at preschool, Celia inquires, "El-wie? El-wie?"
"She's at school," I tell her.
"School," she repeats, nodding emphatically.
Five minutes later, it begins again. "El-wie? El-wie?"
When we go to the mom's group at church, Ellie insists on staying in the baby class with Celia. "She won't cry if I am here," she says.
They also squabble and push and vie for attention, but in the good moments, when their joy in one another is evident, I can't help but wish I had a sister too.
