Pisces is scary when mad. They know just the right things to say to make it hurt. They can make you feel bad about yourself, guilty, scared, worthless, whatever they choose. They are impatient, snappy, and there is no stopping them until they blow their cap and have nothing else to say or do. When a Pisces is mad they can be hard to reason with. They do forgive easily but never forget… internal grudges are not uncommon.
