Oblivion or Irony?

Conversation of the day went something like this:

First girl:  She is always talking back.

Second girl:  How long has she been there?

First girl:  Only a few months.  I think it is so disrespectful.  It's like she can't stop herself, always talking about, always so rude.

Second girl proceeds to talk about another colleague, how rude she is, only thinking about herself.

First girl:  That is so disrespectful.

Definition of irony, both girls were under 30, sitting down on the train and while they were busily talking about disrespect 4 senior ladies were desperately grasping at the straps 6 inches too high above their heads, all within eye level of these 2 highly principled girls.

Yes, I am sure they know all about respect (as it impacts there princess-like selves).
