That's a quote from Jackson, reacting to the news that his Grandma and some of his Texas cousins (i guess all of his cousins live in Texas, now that i think about it) had gotten sick, and to his own sickness.
Now, Caroline is sick. David's been sluggish all day, and Emily has a bit of temperature. Mom & Dad are ok so far. Oh, and Clancy threw up, too, but he didn't go to Texas; he just tried to eat a whole sock.
