Judging a book by its cover; conversation, laughs and lunch during

Have you ever judged someone (or something) on the basis of appearance or clothing or situation?
Has your judgement of someone ever been challenged by some new information which came to light about that person? Their background? Their education? Their experience? A talent of theirs that you discovered? Something they did to help you?
Let’s discuss the classic “Can you tell a book by its cover” question.
Not a lecture, just a discussion.
We'll meet at The Executive Diner, 1400 Duke Street, Alexandria, VA 22314, where we will enjoy a great lunch in their private space as we talk about this interesting topic.
