I am disgusted by a certain kind of people. That is, people who just want to receive infinitely but are unwilling to give at all. It reminds me of a quote from President Kennedy's
address: "Don't ask what your country can do for you--ask what you can do for your
country." Sadly, there are many such selfish people in real life. They are social beetles. We
have no idea (way) to deal with them. All we can do is just stay away from them.
