Boundaries

I cannot understand or comprehend why people feel the need to violate others. Be it emotionally, physically or spiritually there seems to be some people who feel it's ok to tread on others without remorse. Perhaps some people don't respect the limit of others or see the consequences of their actions and how it can effect the other person. I think ones own boundaries are a sacred commodity that should never be sacrificed or manipulated to further someone else's own goals and objectives. Limitations exist for a reason, let it be.
