She had long ago come unconsciously to the conclusion that Trefusis and she were the only members of the party at the Beeches who had much common-sense, and this made her slow to believe that he could be in the wrong and Erskine in the right in any misunderstanding between them.

She had a slovenly way of summing up as "asses" people whose habits of thought differed from hers.

Of all varieties of man, the minor poet realized her conception of the human ass most completely, and Erskine, though a very nice fellow indeed, thoroughly good and gentlemanly, in her opinion, was yet a minor poet, and therefore a pronounced ass.

Trefusis, on the contrary, was the last man of her acquaintance whom she would have thought of as a very nice fellow or a virtuous gentleman; but he was not an ass, although he was obstinate in his Socialistic fads.

She had indeed suspected him of weakness almost asinine with respect to Gertrude, but then all men were asses in their dealings with women, and since he had transferred his weakness to her own account it no longer seemed to need justification.
And now, as her concern for Erskine, whom she pitied, wore off, she began to resent Trefusis's journey with Gertrude as an attack on her recently acquired monopoly of him.
