Always the painful truth.
I myself am notoriously known for providing people with "brutal honesty". People actually come to me to hear bad news. They rely on me to tell it like it is, not sugar coat anything, and be real with them whether it is painful or not.
I consider myself a fairly strong individual, I can handle the pain.
I just can't handle the betrayal when I found out what I believed is/ was a lie. That's the worst.
