you float like a feather

Our GPS, who we've named Madge, is losing patience with us. We try really hard to follow her directions, but sometimes we mess up (allegory much?). When we make a wrong turn I swear the volume increases and in a curt tone she says, "Recalculating," then in complete exasperation she sighs, "When possible, make a legal U-turn." I'm just waiting for the day when Madge says, "You're hopeless, buy a map." Or maybe if she gets really annoyed, "Drive into oncoming traffic you incompetent fools."
