A person's touch, like sneezing, is not what you want to meet. Life is often like this. It is often used to let you know the occasional beauty, loneliness to let you know the preciousness and lack of excitement to evaluate the meaning of existence. Don't be afraid of offending people. Anyone who has principles respects him for three points. Times have changed and good people are no longer welcome. Having a temper is also a true temperament. Swallow back what you said, even if you are mature, but it is your responsibility to say what you should say.
