You'll be surprise when you realise What a person tends to do when he thinks that "no one is watching".
I am trying to give a useful hint here... "actually, there is a camera watching you, you just don't know it!"
Then what you do? Of course, look at the camera and put on your best smile!
There is a lesson to learn.
So what we do when we think no one is watching? Do we put our best words but cruses behind someone's back? Do we pretend to work hard in office only because our boss around?
Before anyone say anything, I would raise my hand and say "I am guilty".
