In Pygmalion, how does the behavior of Liza and Clara compare to Mrs. Higgin's lady-like behavior at her tea party?

The
the tea party in during Mrs. Higgins "at home," there isn't very
much dialogue given to Mrs. Higgins, however she does say a lot before and after the tea party.
The tea party is short and is mostly monopolized by Miss Doolittle. An examination of Mrs.
Higgins' deportment shows she is a lady who thinks of how her remarks and behavior affects or
will affect other people. This awareness of a person's affect on others is way she has banished
Henry from her at homes. An examination of Liza's deportment shows she is absolutely unconscious
of the affect her remarks and behavior have on other people. In this regard, she is precisely
like Professor Higgins and precisely unlike Mrs. Higgins. Clara shares this trait of unawareness
with the pair in that she too has no idea that her remarks and behavior mark her as unpleasant,
though wealthy and well-bred, arrogant and ill-mannered.

Another trait Mrs.
Higgins displays is a readiness to come to the defense and support of one who is under her
patronage, even if only a guest at her tea party for a few minutes. When Liza waxes lyrical
about her father's drinking habits and fears from the general laughter that she has done
something improper, Mrs. Higgins jumps instantly to her aid by saying simply but graciously and
eloquently, "Not at all, Miss Doolittle." The only comparison we can make with Liza is
that when laughed at, she doesn't take umbrage (offense or annoyance) but continues in the same
sweet and open spirit and tone--regardless of subject matter. The only comparison to Clara is
that, having admired Liza's lovely looks and elegant clothes greatly, after Liza has left, Clara
rapturously expresses herself as won over by the "new small talk" that Higgins asserts
Liza is speaking, thus branding herself as shallow, petty, pretentious, credulous and
gullible.
