Why don't college students have lofty ideals and eat, drink and be merry on sunny days?
Strictly speaking, it is not without lofty ideals. College students are at a stage where they are all confused and don't know where to go. They need to consider many practical problems, so they can't talk about any ideals, and most of them are unrealistic, such as wanting to be actors, the king of pop, or the terminator with super powers in movies. Ideal is hard to realize, but freedom can make a frustrated young man relax.
