This was a light bulb moment... so close to reality.
Many times its hard to please some people (guess that is why dogs are so popular as pets, they give you the gift of being pleased with you, no matter how stupid you may sound ;).
On the other hand, we too either dismiss someone instantly, or take a liking for a person immediately. There are fewer in-between connections.
One of the most important learning (which comes gradually) is that we need to be aware of this tendency and moderate it. That is when we start getting wiser...
