Those are cute nerd glasses. Time for obscure 80s movie reference:
Monique Junot: I figured if we had nothing to say to each other he would get bored; go away. But instead he uses it as an excuse to put his testicles all over me.
Lane Myer: Excuse me?
Monique Junot: You know, like octopus? Testicles?
Lane Myer: Ohhhh. Tentacles. N-T. Tentacles; big Difference.
An argument is two people sharing their ignorance.
A discussion is two people sharing their understanding, even when they disagree.
