the backseat whisperer

any time we're in the car, we always hear this weird whispering in the backseat. so strange how he does that. it's kind of funny and kind of creepy all at the same time. it makes me laugh, though. who knows what he's talking to himself about! between whispers we'll randomly hear him shout: "digger!" or "green garbage truck!" or "volkswagon bus!" sometimes when there's a bunch of his favorite cars/vehicles, then he starts shouting them faster and faster until his excitement builds and it seems like his head will explode. it's quite amusing.
