Nope. That said, some universities and colleges may seem that way.

Yeah... uh don't believe everything you see in the movies!!

From my time in China, I know that few Chinese can do the things that Jackie Chan can do. In the same way, not all Americans party every weekend. Actually, there is a party gland, which secretes hormones that enable young people to party till 2:00 am. It secretes less as you get older, till at about 40 years old, you stop partying altogether. It's sort of like menopause. At 63, I can testify that this is a fact. I went to bed at 10:00 pm on New Year's Eve and let other people celebrate.

Don't believe everything in movies! Some americans party but some people don't. Many people are different. I don't think everyone parties. ^_^

I definitely don't party. XD
