    <p>Last night Sarah went on a barking rampage when she heard
    noises on the side of the house.  Apparently they were very
    different noises from the ones she knew, even though they were
    the same neighbors (and their friends) making said noise.
    Something about the neighbors being up on their roof really
    annoyed Sarah.</p>

    <p>Sarah has been known to bark ferociously at a possum in the
    back neighbor's tree.  Said tree may be consuming the utility
    pole at the edge of our back yard.  The possum just sits in the
    tree (or on a wire) and taunts the poor puppy who can't reach
    her.  And occasionally poops at her too.</p>

    <p>My only guess is that something about relative elevation
    really annoys Sarah.  I don't suppose anyone else has a better
    explanation?</p>
