quoted off from somwhere...

Trust is a fragile thing. once earned, it affords us tremondous freedom. but once trust is lost, it can be impossible to recover. of course, the truth is, we never know who we can trust. those we’re closest to can betray us & total strangers can come to our rescue. in the end, most people decide to trust themselves. it really is the simplest way to keep from getting burned
