Lady Bracknell is surprised by a gentleman
"Aren't you a friend of Mr D, who used to work in Liverpool, but who is now working in Portsmouth?"
Lady Bracknell confirmed that she is indeed well-acquainted with the charming Mr D, but that she was at a loss to imagine how the bearded gentleman could possibly have divined that fact.
"Oh, he described you to me", came the response.
Unless Lady Bracknell misses her guess, she believes there can be only two logical explanations for her having been so easily recognised.
Either Mr D's powers of description are more than ordinarily impressive, or Lady Bracknell is so distinctive in appearance that even a cursory description of her will serve to brand an image so firmly in the cerebral cortex of its recipient that she could never be mistaken for anybody else.
Lady Bracknell is not convinced that this is a good thing....
