Your post reminded me of the time I dropped a Bart Simpson and all I said for a few hours was, "it's all fucking circles, everything, just fucking circles."
Or, as I responded to my kid when she came home from school, annoyed, saying: "so and so did such and such to me, I'm going to do it to her, see how she likes it!"
"Why would you copy the behaviour of someone you don't particularly like? Do you want to turn into her?"
