Kindness is beautiful, but you need something more to deal with toxic people. It's important to know when you are being manipulated, it's good to be soft-hearted but don't let others take that as a weakness. I am not sure who needs it, but hopefully it'll give you space to think of it from a different perspective.

Good advice. It can be difficult to navigate at times.
