"Anne says whoever is happy will make others happy too." Do you agree why or why not?

I most definetly agree with Anne on this statement, because when you are happy and then when other people see that you are happy, it makes them feel happy for you and makes them feel good. But not everybody is happy. Some people get really jealous, because the other people are happy and they are not. But some people choose not to be happy. But I agree with Anne when you are happy others are happy too.
