Jealousy comes in many shades, from the lightest grey to the darkest black. In every form, it poisons the heart filling it with pain. Once it's reached deep inside you, it almost never goes away. It creeps up your throat, during the most unexpected of days, forcing you to spill the most hateful words, things you didn't mean too say. This is how it spreads. It pours from one heart right into another.
