The first time you get into a hybrid car, it can be quite eerie.
Not merely because of the peculiar sanctimoniousness of its owner, but because when it comes to a halt, there seems to be no engine sound. At first, you think it's stalled. Then you realize that cannot be. So your innards have to train themselves for this odd sensation.
However, it seems conclusive now that this little lamb's silence is proving to be somewhat injurious.
