Courtesy can assume ridiculous forms. Take this example of passing communication for instance.
I was descending the staircase after class. I saw a girl climbing the stairs my way. There was no one else in the vicinity. She looked at me. I looked back at her. She didn’t look away. I smiled at her. She smiled back. I smiled back again. She greeted me, “Hey! How have you been?” I replied “Good! What’s been up with you?” She replied, “Usual, catch you around later anyway… Gotta rush for a class”. I bade her farewell, “Sure, see you around later”. We crossed each other. She left for the class and I left for the grounds.
And I am almost certain that neither of us knew the other.
