College drinking

I think it's amazing how someone could want to drink so much on a regular basis that they can't remember half the thing that try do most weekends. I don't understand why drinking such excessive amounts of alcohol is viewed as a fun thing to do with friends or other people and why people in college and high school drink and drink as much as they do weekend after weekend. There's nothing wrong with having a couple of drinks but people need to know when enough is enough but no one ever learns from others mistakes.
