In company take care not to speak much and excessively about your own acts or dangers: for as it is pleasant to you to make mention of your own dangers, it is not so pleasant to others to hear what has happened to you. Take care also not to provoke laughter; for this is a slippery way towards vulgar habits, and is also adapted to diminish the respect of your neighbours. It is a dangerous habit also to approach obscene talk. When then anything of this kind happens, if there is a good opportunity, rebuke the man who has proceeded to this talk: but if there is not an opportunity, by your silence at least, and blushing and expression of dissatisfaction by your countenance, show plainly that you are displeased at such talk.
