What the what?

So I've got the flu and have been coughing up half my lungs for the past two days. Ellie is very concerned about my condition and comes to hug me whenever I have a coughing spell. Today, however, she was sitting at the dining room table eating grilled cheese and considering eating soup when I was on the couch languishing. Suddenly, I coughed_really_hard.

"What's wrong, Mommy?"

This is the first time that Ellie has been able to initiate a question, appropriately, about something she didn't actually witness (she only heard it, didn't see it, and she's really more of a visual learner). She doesn't do abstract. But she asked, so plainly, so definitely, that I cried. After I answered her, of course.
