The human instintcs of Trust and Distrust are so easy to be descibed in a single situation. A situation as simple as sleep, can help as an example. A real life example.
A friend of mine has a hard time to wake up in the morning, even harder to get out of the bed and go to work.
People can be so distrustful when it comes to sleep. We have a driver who picks us up every morning. Now, it so happens that the driver is so untrusting that he will call my friend 30 mins prior to the pickup time. It was all good, till he realized that my friend received the call and yet after the call, went back to sleep. This happened a few times and the driver soon realised how unfruitful it was.
Our driver is a smart guy. He now asks for a photograph which can show a reflection of my friend in the bathroom mirror, brush in the mouth and will not disconnec the call before he gets such a photo.
This is what I call dedication to work and helps my friend be on time at his office.
