This is a test of commonsense. Complete the next sentence:

How to get along with your brother or sister
Think before you speak.
Though it isn't always easy, thinking before you speak is important in improving the communication between you and your siblings. It not only prevents things from escalating into an argument, but can keep you from saying words you'll later regret.
When you feel yourself getting angry take a moment and count to 10. If you still haven't calmed down, excuse yourself and leave the room.
