I am studying Accounting and Finance. And that has always been the way I tell people about my degree. I study Accounting and Finance. I use its full name.
However, people commonly refer to me and my colleagues as Accounting students. People in my college. People in my school. People in my university. People in my society. People, generally. They all call us Accounting students.
But, there is an exception to it. Some of the people refers to me as a Finance student.
Yes, this took me by surprise at first.
And having completely subscribed to the idea that people have different worldview, I began to understand them.
