The old girl must have had an impressive scowl

Apart from the ceaseless anxiety of having to keep and eye skinned for elephants, I found myself much depressed by barking dogs, and once I received a most unpleasant shock when, alighting to consult a signpost, I saw sitting on top  of it an owl that looked exactly like my Aunt Agatha. So agitated, indeed, had my frame of mind become by this time, that I thought at first it was Aunt Agatha, and only when reason and reflection told me how alien to her habits it would be to climb signposts and sit on them, could I pull myself together and overcome the weakness.
