What is the proper etiqutte of using fork knife and spoon?

Basic etiquette is just common sense. Use your fork to spear things of a solid consistency. Use you knike to cut things and spread butter , soft cheeses, jam etc. Use your spoon for liquids , like soup , or very soft things like ice cream or Applesauce . NEVER put your knife to your mouth . This is tacky , and possibly unsafe. Never put any utensil into a common dish that has been in your mouth. This is a potential source of cross-contamination.
