Astrology
The lines can get blurry.
But directly stating your expectations and limitations is much easier said than done.
Unlikeno-nonsense Saturn, which is a strict boundary enforcer, Neptune is more like a boundary dissolver.
These mutable water signs areruled by the illusive and hazy planet Neptune.
So its not that Pisces are afraid to set boundaries.
Its usually that they struggle to identify what their boundaries are.
