Responding to Katie Russell's Question

Katie asked "What do you think, is there such a thing as a trust worthy person" 

 I personally feel that there is a trustworthy person, though the want to trust and be trusted is part of the selfish nature of human nature.

             To be able to be trusted by someone, I feel you have to have had put your trust in someone else.

Google defined trust as: to have confidence or faith in also having reliance without fear.

Again, I feel that there is a such thing as a trustworthy person, just finding that person can be a mission.

 Though I cannot really explain why I feel there is a trustworthy person, I believe it is so.  There is such thing as a non-trustworthy person, so if that is so, there must be a trustworthy person.

I have the most trust put in my older sister; and the bond that we have is impossible to break.  I can tell her anything, and I tell her everything.  I know that if I need anything, I can go to her.  She would never do anything to intentionally hurt me, and vice-versa. 

I feel that is a way to describe a trustworthy person.  If you can describe something using realistic terms, I feel that it does in fact exist.

Question: Can you personally be trusted if you haven't given your trust to someone else?  How does being trusted and giving your trust go hand-in-hand?
