Trust. A little word with an immensely big meaning. Trust makes us feel safe, allows us to venture out of our comfort zones, and to form relationships. But when trust is broken, the consequences are catastrophic.
Human to human trust is tricky. What is a safe level of trust? It's not the same as trusting a pair of training wheels to do their job. When human to human trust is broken, the hurt runs deep where it often remains and lurks. The deeper the trust, the harder the fall.
In the ideal world, trusting one another wouldn't be so frightening. If you trusted someone with your heart, it wouldn't be returned in pieces. In the ideal world, Iago's would stay in Shakespeare's literary fiction.
