“Who says I am not bitter?”: This is from a Seinfeld episode “The Fix-Up”. It is very funny. Elaine’s friend says: “…but I feel badly for my mother. If my mother weren’t around it wouldn’t be so bad. But I’m telling you if I’m not married by the time I’m 40, I’m gonna have to kill her because it’s the fair thing to do.” Actually I watched a French movie long time ago which seemed to be based on a true story. A family had a dream to send their son to medical school. The son didn’t past the test and didn’t get in, but pretended to go to medical school every morning just so that the parents would not be disappointed. This lasted for two years until one day the son couldn’t take it anymore. Still, he couldn’t face his parents’ disappointment. So he bought a gun and killed his family.
