Rachel, six years old, is watching Dora the Explorer with Sammi, three years old. Sammi is enthusiastically responding to everything Dora asks. At one point, as they do every episode, Dora consults Map to find out which way to go. Map tells them they have to go over the troll bridge, over the big rock and then get to the library. Rachel looks disgusted.
"Why don't they just go around the big rock?" she asks.
Clearly, someone has outgrown Dora.
