Talk WITH them. It is people caring about what happens to each other and letting it show. Maybe somebody is having a tough time at school or is doing well on the baseball team. Whatever it is, take time to show that you notice and care. It is people getting angry at each other, but still loving each other.
People DO get mad at each other.
But the important hting is whether you can let off the steam without losing your love for each other. It is people allowing for the differences among one another. Learn to recognize them and appreciate the ways each person is special and unique. It is people laughing and crying without feeling ashamed of it. When you really love and share and understand, you have nothing to be ashamed of.
