One. You started the "isn't it quaint how stupid Barnaby is?" conversation with Lilith.
Two. When you do something that obviously offends someone and your intention isn't to upset them more you apologize. You don't justify it, you don't dance around "if you took this offensive thing to be offensive then that's on you". You just fucking apologize.
Three. This isn't about class.
Four. You saying I don't think before I talk is looking pretty damn rich. That's two out of three in one night that you've pissed off.
And while I'm at it -
Five. You and Lilith can go get a drink without the quaint ridiculous lush. Feel free to express your shock to her that I have emotions.
