I get told this or one of its variations on an almost daily basis, by my girlfriend/fiance. I take it as a compliment.
I also think it is kind of true, due to some of my traits and philosophies. For example, I would never cheat on her, and while she can never know that is true for a fact, she can assume it is true based on how she sees me act. In all the time we have been together, she has never even caught me looking at another woman, the reason being that I have not looked at any other women.
I have also been described at “recklessly honest” by many people. She knows, that while I am totally full of shit and lies towards many people, that I have never lied to her. She knows she can count on me for a blunt and to the point answer, regardless of consequences.
In a lot of ways, I think I am different to most people. Having said that, most people are probably different to most people anyway.
