I seem to be an all or nothing kind of girl when it comes to trusting people. Either I open my heart up to you completely, taking you and face value, trusting in everything you tell me (and often getting my heart broken because that trust is misplaced)......or I draw inside myself, putting up that wall, refusing to let you get too close, until you have earned my trust.
Believe it or not, I actually prefer the first option. Yes, it can lead to pain, but the second option leads to isolation and loneliness. I'd much rather trust people, and sometimes be wrong....because if you never trust anyone, then you never have anyone who really knows you and can be your true friend.
