The fact that they are so committed to fairness, though, makes them trustworthy.
Even though they aren't the biggest fans of gossip, they'll listen to you rant anyway because they know that sometimes you just need to get things off your chest.
Others enjoy it because they enjoy being an objective bystander to interpersonal turmoil that has no bearing on them.
Whatever it is that you want to tell them, they will gladly listen to your tales of woe and triumph.
Because it keeps them better informed about what's going on among their pals.
Pisces will maintain a secret not only out of deference to the other person, but also because they hold your friendship .
They will gladly maintain any confidence you share with them if it will strengthen your bond with them.
Since they fear losing you and would feel terrible if they caused you pain in any way, Pisces will avoid doing anything that could threaten.
