College students get stereotyped in 4000 different ways. Think about it. You can name 10 stereotypes without even thinking. The party animal, the frat brother, the honors student so on and so forth.
But if you really want to get to know a college student, look at their minor. A student's minor tells you who they are, who they wish they could be, what they love, just by one word.
A person chooses a major they know will lead to cash money after graduation. It's usually something they are good at, not something they enjoy doing.
But the minor is the window to the soul. It allows for us students to study what we love, without having to explain to our family what in the world we are going to do with a degree like theatre or, no offense, philosophy.
I personally am an English studies minor, aka, I read literature. I love books, but book reading is not a very lucrative future career. Minors let us cheat the college degree system and study what we love, not what society loves.
So for a future college movie idea, look to a minor area of study. It usually tells a major amount about a person.
