Emotions [PDF ebook] 

Everyone experiences emotions every day. Some emotions are simple feelings about things that happen, such as excitement at a live concert. Others are more complicated, such as the mixture of joy and sadness we might feel when we change school. This book shows how emotions are vital for human social behaviour, being at the heart of our relationships with families, friends, and other groups, and how they affect the way we interact with the world around us.
