I've made a vow to read 25 plays and 200 poems before reading any fiction (the exception is during snippets of waiting time), and I'll try to comment on every play I read.
Henrik Ibsen's A Doll's House makes me feel bad for being a husband. It's also a masterfully written drama.
If I ever write an academic book, it might be on suicide in literature. It seems to come up fairly frequently in literature with various meanings. Some of my academic work has involved suicide in literature (in a grad school class on the Holocaust I focused two papers on suicide in the Holocaust, there's a failed suicide attempt in The Magus that I talk about in my thesis on John Fowles, I teach Hamlet, yada yada yada. Then again, suicide is such a prevalent theme in a lot of canonical literature that every English prof could probably say taht his/her academic work involves suicide in literature.
