““It is not necessary or advantageous to give your opinion about everything to everyone. It is not your job to be a form of cheap entertainment for those around you. This is a trap that is very easy to fall into and is the downfall of many people. While it is certainly okay to chat with your buddies or other people about meaningless things in order to be affable, you should be careful of your conversation even on such relaxed occasions. It is all too easy to get carried away with your conversation and express opinions which can be offensive and used against you at a later time. Be genial and social, but at the same time be aware and thoughtful concerning your private beliefs.””
