I'd probably want to teach at university, because children would drive me insane. I suspect it would be English literature, Shakespeare and so forth. I've always been deeply, deeply in love with that kind of thing.

This quote is from someone who wants to teach college level courses and is particularly interested in teaching English literature. They think it would be the best fit for them and that they have a great fondness for English literature, especially writings by authors such as Shakespeare. They think teaching college level courses would be better than working with children, as they think children would drive them crazy.
