One of the ways I know that I lean toward introversion is my experience at reunions. In journals and poetry, I describe those events with both a longing and regret over what I might call invisibility. "Disappear Here" is the name of the poem. No doubt, it was inspired by the "people are afraid to merge" theme in Less Than Zero by Bret Easton Ellis. Some people are afraid to merge; at least, I know one.
I also answer the question: how do you know if you are a bigot?
