living in an ivory tower

To be living in an ivory tower means to be living in a place where you can be aloof from the realities of living. A person who is very isolated, standoffish and desolate from others are said to be living in an ivory tower as they dont have much care for what is going on around them and the place they are living is quite detached from the rest of society. This is commonly used when referring to someone living in a university where they stay in their room and it is unlike normal living.
