In our life, we will be nice to other people, while when facing our parents, we are impatient and even argue with them. People always think their parents don't understand them and refuse to talk to them, they show the worse temper in the ones who love them and will never leave them, but they show their kindest fact to the strangers. It is a sad thing, the reason that people show their badness to the dearest lies in that people just get used to the presentation of their relatives, they know in their hearts that their parents won't leave them, no matter what they do. Our relatives will never leave us, they take care us all the time, they are the dearest persons in the world. People neglect it, so we should be nice to our parents, love them and communicate with them.
