Be appropriate. Crying in front of your child when your dog dies is appropriate. Screaming because you didn’t get the parking spot you wanted is not. Kissing your spouse in front of your child is appropriate, making-out is not. Current fashions can be worn without being an exhibitionist. By being appropriate at all times, you are a good example for your children and for all the people you will encounter throughout your day. This will also put others at ease in your presence, and it’s simply good manners!
