Don't ever underestimate the angry side of a pisces. They put up with ALOT. When they finally snap it is bottled up anger letting loose. Let me tell you it is not pretty they know just the right words to really hurt you. They are not afraid to say nasty things to make you feel the way you made them feel. You might be in shock because they usually are empathetic and kind but can become ruthless and cold when angry. Yes they are sweet but there is also a very sour side.
