Hearts in cages

Hearts are wild creatures. They don't do well with rules and are rarely willing to compromise. They are illogical in what they feel. The emotions they bear are quite intense. They break easily, but can be difficult to unearth. They can be gentle, compassionate, understanding, comforting, and delicate. Other times, a raging storm, burning with passion, aggressive, cold, and unforgiving. The emotions wage war and can be deadly. Maybe this is why hearts are kept in cages
