The CSO and I are the friends mentioned here.
Tongiht, I ended up giving a rude lady the bitchface.
I was coming out of a big chain store and the cashier told me Happy Holidays.
"Yeah, you too..." I muttered.
So far so good. But she said "Happy Holidays" to the next lady in line, who responded "And Merry Christmas to you!" in a snappish tone of voice.
So rude lady got the bitchface.
