A Small-Medium suburb in Pittsburgh, commonly known to have many spoiled/preppy kids. Some kids are quite isolated but some also are some of the most knowledgable kids you will find in a high school. Refered to as the "Bubble", or "Lebo". Also, many kids like to think they are knowledgeable and are going to "break the bubble" but are actually showing what people mean when they call it the bubble.
Overall, Mt. Lebanon is a fine place to grow up if you have the right friends/parents but some kids could defintaly mature.
