I tend to trust quite a few people, including friends and family. However, that isn't to say I trust everyone. There are somethings I know who to say to and who not to say to. My trust varies amongst people, so some I may trust more than others. However, if I were to tell someone that I trust them, then it means I trust them or else I would have no purpose in saying so.
As for family, the same thing applies. You cannot always trust your family, regardless of them being of same relation, that isn't to say they can go behind your back. So again, my trust varies amongst people, and most of the time my trust relies upon my friends who I've known for years and my parents.
