Reading this article made me recall an incident back in art college. A mature student asked if I smoked cannabis, I said I do. There was another mature student in the room with us. Upon hearing my confession she stared at me with a very serious expression, then lunged forward at me and pushed her face into mine. I was so taken aback I nearly fell off my chair. I had never met this woman before, we were never introduced and I haven't seen her since.

I would argue this woman was sufficiently arrogant that she thought it was socially acceptable to invade my personal space because I was a stoner. Perhaps I myself was more arrogant when I was younger, in the spirit that user warent mentioned below. On the other hand, I'm not the type to spontaneously invade the space of others.
