STRASBOURG, FRANCE - MAY 18: Italian students from the Primo Levi Technical Institute of Vignola in the Modena Province, toast with glasses of beer in a pub during a school trip to Strasbourg, France to visit the European Parliament on May 18, 2004. School trips can be a sort of initiation trip for teenagers, where they are introduced for the first time to alcohol and drugs. Many times they don't sleep for the whole trip. The trips often allow the students to get to know each other better. If one is considered "different" than the group, it can be a nightmare experience for the teenager. Mainly the teenagers are only interested in clubs, shopping and having a pizza instead of the cultural aspects of the school trip. (Photo by Marco Di Lauro/Getty Images)
