Right?

Be they acronyms, terms or expressions, communities share words. In my community, many of us end comments with "right?" Students do it. Even professors do it. Like "um" or "ahhh," when I start counting, I get edgy. Right does not make might. The leap here, I believe, is to express my thoughts without a need for affirmation. Can I say something and then have the courage to bathe in the silence? Right? Right?
