Check out the homepage of the Washtenaw County Chapter of the American Red Cross - featuring Hallie!
Because the picture won't be up forever, here's a screen capture. Hallie wants you to Get Trained to be her babysitter. Presumably so someone other than her neglecting parents can wipe the slobber off her shirt.
So Hallie joins her bro as a Red Cross model. Here's a related thing that's pretty cool: this recent blog post, which mentions the Red Cross, was found by the National Red Cross during a websearch for all Red Cross references on social media sites (facebook/twitter/blogs), and was included in an email that was sent to communications employees around the country. Erin's coworker received the email and recognized this guy at once!
