An excerpt from this book

Jealousy is that peculiar, itchy sensation you feel when your best friend announces they have just been gifted a golden retriever puppy, while you are currently nursing a lukewarm cup of instant coffee and wondering if your houseplants are staging a quiet, leafy protest against your neglect. It is the human equivalent of a cat hissing at a vacuum cleaner, except the vacuum cleaner is a promotion your colleague received, and the hissing involves a complicated cocktail of resentment, self-loathing, and the sudden, irrational desire to hide your colleague’s stapler in a ceiling tile.

This book is a comprehensive guide to decoding your emotions and building secure relationships.
