There was a little book sold in the bookstore called Christian Etiquette by Dorothy Owens. It was probably about 50 pages or so. It had a lot of advice on things like how to set a table, what fork to use, proper dinner conversation, etc. Most of the trivial details have become antiquated in today's society. The overall concept it stressed, though, remains true. Our "etiquette" should be concerned with making people feel at ease and should never create an atmosphere of stress. I would recommend the book and reiterate it should be used with that thought in mind.
