First impressions are extremely powerful and, more often than we might admit, are perceived as reality. In fact they are merely a shadow of the truth. A shadow on the wall may give you a pretty good outline of a person's face, but it is certainly not an accurate description. A shadow can be very misleading. What we might perceive as a dog, could in reality be a child's fingers twisted in front of light.
You know the story of "Plato's Cave". Prisoners from birth are chained in front of a cave wall and see nothing but shadows cast on the wall as their guards walk between them and the fire. The shadows are all they know. Someone telling them what exists outside the cave is considered dangerous because he threatens their concept of reality. It reads, "---And if they were somehow able to get their hands on and kill the man who attempts to release and lead up, wouldn't they kill him?"
Reminds me of the verse in Scripture, "Men loved darkness better than light-."
There is a spiritual "reality". God, Jesus, the Holy Spirit, heaven, hell, angels and devils. Don't be surprised if those living in darkness have a tough time listening to you.
In the film "Fatal Attraction" Dan's first impressions of Alex were tantalizing. He got more than he bargained for. A huge difference between the "shadow" of an attractive colleague and the psychopath who kidnapped his child and tried to murder his wife.

Our first impressions need to be taken for what they are, a mere shadow. Don't fight the truth, get out of the cave and into the sunlight and experience a real dose of reality.
