Some people will think you are a genius, others will think you are the opposite.

You might need to think more about saying certain things around certain people. It's a normal part of maturing. Think before you speak so as not to be offensive. But do not lose your sense of humor. Laughter is so important in life. Sarcasm has it's place, but so does being serious. If someone doesn't get your sense of humor, don't worry about it. It's their loss.
